Personal Hedgehog, Career Philosophy, and Leadership Principles

A personal reflection inspired by Jim Collins’s What to Make of a Life

Executive Summary: The Life and Career I Want

My core aspiration

I want to take ownership of important business problems and create measurable results through products and execution.

For me, growth is more than acquiring knowledge or deepening expertise. It means becoming more capable by solving consequential problems and seeing those solutions make a tangible difference.

My current understanding of that ambition sits at the intersection of three circles from Jim Collins’s book What to Make of a Life:

• My encoding: Structuring complex problems, finding the critical bottleneck, and mobilizing people and systems to address it.
• My inner fire: Understanding customer problems, putting solutions into practice, and seeing the impact in metrics and customer experience.
• Career growth: Improving critical business outcomes while developing my capabilities along the way.

This is a working hypothesis, not a final answer. I want to keep testing it through the roles I take on and the results I help create.

Part 1. Self-Understanding: What Do I Want?

1. What kind of life do I want above all?

A life of growth—not simply one in which I know more or accomplish more, but one in which I take on important problems and become more capable by solving them.

2. What is the encoding hidden within me?

So far, I see three recurring strengths.

Structuring complex problems

I am good at breaking down ambiguous problems, understanding how they fit together, and identifying their root causes.

At McKinsey, I developed a disciplined approach to doing this: define the problem, form hypotheses, test them with data, and turn the findings into actionable solutions. But analysis is not an end in itself for me. It matters when it helps solve a problem that matters.

Finding the critical bottleneck

Complex problems rarely allow every issue to be solved at once. The key is to identify what most constrains the outcome and focus limited resources there.

At Toss, for example, I brought together merchant operations data and information on FacePay rollout readiness, then translated adoption barriers into specific failure types and actionable workstreams. The data was scattered across organizations, and there was no common identifier. I helped create a way to see the problem clearly and connect the people who could act on it.

Bring people together to make the change happen

A strong analysis or strategy is not enough for me. I feel a greater sense of accomplishment when teams and partners act, products or operating models change, and results improve.

This helps explain why I am drawn to hands-on business operations and product ownership more than to roles where my contribution remains indirect.

My strength, as I understand it today, is connecting structured problem-solving to execution.

3. How do I work most effectively?

My natural problem-solving process looks like this:

Define the problem → Find the bottleneck → Design a solution → Align people → Execute → Measure → Improve

I start by clarifying what actually needs to be solved, then identify the constraint that matters most. From there, I turn the problem into decisions and workstreams, align the people involved, and help translate the plan into changes in products, processes, or operations. I then measure what changed and use the results to determine what to do next.

The link between defining the problem and carrying the solution through to results is especially important to me. I do not want to stop at analysis, nor do I want to execute a plan without shaping the problem it is meant to solve. I want to take responsibility for the full arc—from deciding what matters to implementing a solution and learning from its impact.

That is the kind of product and business ownership I want to develop.

4. Am I spending my energy in the right way?

I feel most engaged when I can understand a customer problem firsthand, change a product or operating model, and improve business metrics.

I want more opportunities to:

• Discover and define customer problems
• Own product / business goals and key metrics
• Set priorities and determine how to execute
• Work across teams to change products and operations
• Measure outcomes and improve them over time

I want less work where I contribute indirectly without the authority or accountability to affect the outcome, where the deliverable itself becomes the definition of success, or where polishing materials and demonstrating activity take precedence over solving the underlying problem.

Part 2. My Inner Fire: What Makes Me Feel Most Alive?

5. What work would I choose even if it involved significant stress and hard work?

My experience so far points to a clear answer: I feel most energized when I solve a problem and see the numbers change.

Two elements are essential.

Understanding the customer. I enjoy finding out what problem a customer is facing and why the current product or operating model fails to solve it.

Implementing a solution. I want to go beyond understanding the problem. I want to change the product or the way work gets done, then see the customer experience or business metrics improve.

At Toss, I experienced what it felt like to work with an almost euphoric level of focus. That experience showed me how motivating it can be when both elements come together.

6. What makes that work fulfilling?

The moments that stand out are when I uncover the core of a complex problem, find a way to solve something customers struggle with, change a product or operating model, and bring people together to make the change happen.

Seeing the result in metrics and customer responses matters—but so does my role in creating it. I find greater satisfaction in knowing that I helped define the problem and implement the solution than in simply seeing a good result occur.

For me, meaningful work combines tangible impact with real ownership of the process that produces it.

Part 3. Connecting My Experience to Future Growth

7. What capabilities can I build on?

I have accumulated complementary experiences:

• McKinsey: Problem-solving and strategic thinking
• Kellogg: Broader business knowledge and perspective
• Toss: Product and operational problem-solving, cross-functional execution, and measurable outcomes
• MarqVision: AI product marketing, positioning, and global go-to-market

I want to connect these experiences into a coherent capability rather than leave them as separate chapters of my career.

The differentiation I aspire to is not strategy alone or product execution alone. It is the ability to structure complex business problems, solve them through products and operations, and translate those solutions into measurable results.

Part 4. The Hedgehog: Where the Three Circles Meet

8. Have I found the intersection of my encoding, career growth, and inner fire?

My current hypothesis is this:

Own important customer and business problems, change products and execution systems, and create measurable results.

This direction brings together the three circles in different ways.

• It fits my encoding: I can use my ability to structure complex problems, identify bottlenecks, design actionable solutions, and mobilize an organization.
• It creates economic value: It can improve metrics such as adoption, activation, retention, revenue, and operational efficiency, while deepening my understanding of customers and markets.
• It fuels my motivation: It lets me understand customer problems directly, implement solutions, and see the effect on real outcomes.

The roles that seem closest to this intersection are those with direct ownership of product and business results. The title matters less than the problem I am responsible for, the authority I have, and how directly I can influence execution and outcomes.

9. What is the one big thing I want to put at the center of my life?

It is not a particular company or job title.

I want to solve consequential customer and business problems directly and create tangible results through products and execution.

To do that, I need to move beyond roles focused primarily on analysis and advice. I want experience owning goals, setting priorities, and being accountable for execution and outcomes. I also want to learn how to work with others, draw on their strengths, and achieve shared goals.

Part 5. Cliffs and Fog: What Career Turning Points Have Taught Me

10. How have major transitions reshaped my view of work?

My career has included several turning points that challenged me to reconsider what I value.

Leaving McKinsey for Kellogg

At McKinsey, I learned to structure complex business problems, identify root causes, and develop logical solutions. That remains a foundation for how I work.

Over time, though, I wanted to explore more than how to become better at what I already knew how to do. I wanted to understand what kinds of problems I wanted to spend my life solving.

Going to Kellogg gave me room to step outside a familiar environment. Through people with different backgrounds and exposure to the tech and startup ecosystem, I began to see that my options extended beyond the career paths I already knew. Building products and businesses—and changing outcomes through execution—became a concrete alternative.

Choosing Toss over a return to McKinsey

Because McKinsey had fully sponsored my MBA, returning there seemed like the rational choice. I chose Toss instead because it offered the chance to work more directly on product and business problems.

Looking back, that decision was a turning point. I learned how satisfying it could be to turn strategic thinking into real changes in products and operations, and to see those changes produce results. It gave me concrete evidence of the kind of work that energizes me.

Moving from Toss to MarqVision

MarqVision offered a chance to join a global AI startup and broaden my experience into go-to-market and product marketing. After working on the product and operations side, I wanted to understand more of the business: markets, customers, positioning, and how a product's value reaches them.

That experience has broadened my perspective on how products are brought to market.

What I have learned

Each move has expanded what I understand and what I can do. But I have also learned that not every kind of expansion is equally suited to me.

My next step should not be about adding another skill or broadening my experience for its own sake. It should help me apply my strongest problem-solving capabilities to outcomes that matter.

Part 6. Luck, Opportunity, and Seeds Worth Reviving

11. What have I made of the opportunities I have been given?

My career has been shaped by my own efforts, but also by the opportunities and environments I have encountered.

McKinsey taught me to solve complex problems. Kellogg broadened my view of business. Toss gave me the opportunity to solve product and operational problems directly and deliver results through execution. At MarqVision, I am learning about AI products and global go-to-market.

The challenge now is to combine these experiences rather than leave them as separate entries on a résumé. I want to use them together to become better at solving complex business problems.

I cannot predict or control every stroke of luck. But I can choose what I learn from each opportunity, what I do with it, and how I carry that experience into whatever comes next.

12. How can I balance expansion with a return to my strengths?

My career needs both.

Expansion has meant learning about different parts of a business: moving from strategy into product and operations, then into go-to-market and product marketing. Each transition has helped me understand the business from a different angle.

Returning to my strengths means bringing those new perspectives back to the work I find most meaningful. My experience in product marketing and go-to-market has deepened my understanding of customers, markets, and communicating product value. I want to apply that understanding in roles where I can once again take responsibility for product and business outcomes.

I do not want to keep expanding simply for the sake of expansion. Nor do I want my career to amount to a collection of separate experiences in strategy, product, operations, and go-to-market. I want to bring those perspectives together to solve the problems that matter most to a business.

Part 7. Responsibility, Leadership, and Principles for Life

13. What is my leadership encoding?

My current hypothesis is that I want to be:

A leader who brings clarity to complex problems and creates the environments for people to work toward a shared goal.

That means more than assigning tasks or tracking progress. It starts with defining the problem that matters and clarifying the goals and priorities. It then means creating the structure people need to understand their responsibilities and execute effectively—and finally, looking at the results and improving what is not working.

Three conditions seem essential:

1. Clear direction: People understand what we need to achieve and why it matters.
2. Real ownership: Responsibility and authority are aligned.
3. Results-oriented execution: Success is judged by the impact on customers and the business, not simply by the volume of activity.

I want to develop not only my own problem-solving abilities, but also the ability to help others use their strengths to deliver better results.

14. How can I understand other people's encoding and inner fire?

I do not assume that everyone is motivated by the same things I am.

Some people are energized by solving complex problems; others by working closely with customers, developing deep expertise, or helping a team grow. A leader's role is to understand those differences and shape roles and responsibilities so that individual strengths contribute to shared goals.

That starts with questions such as:

• What kinds of problems give you the most energy?
• What work do you do naturally better than others?
• Which responsibilities let you take the most initiative?
• Are your strengths and motivations being fully used in your current role?

If I lead a team, I want to set clear goals and success criteria while giving people room to use their strengths in how they achieve them.

This is still a capability I need to develop. I will need to test whether I can translate my own strengths in problem-solving and execution into better outcomes for people and organizations.

Part 8. Reexamining My Beliefs

15. What beliefs about life has this book challenged?

The most important shift has been in how I evaluate career success.

I used to place considerable weight on externally visible factors such as a company's reputation, global experience, and growth potential. Those things still matter, but they do not fully explain whether the day-to-day work will be meaningful to me.

My experiences across different roles have helped me see more clearly the kinds of work in which I feel most engaged. Going forward, I want to weigh external conditions alongside a more honest understanding of what kind of work fits me.

I have also redefined growth. It is not simply learning more or earning a higher salary. It means solving problems I consider critical, creating real results, and developing my capabilities along the way.

16. If another “Natalie moment” comes along, how can I recognize it?

Moving to Toss after my MBA was one such moment. Returning to McKinsey seemed rational, given that the firm had fully sponsored my degree. Instead, I chose the opportunity to work directly on product and business problems—and learned a great deal about what energizes me.

The lesson is not that intuition is always right. It is that I should examine what draws me to an opportunity, how that attraction connects to my actual past experiences, and whether I am willing to accept the trade-offs.

If a similar opportunity comes along, I want to ask:

• Is it connected to problems I consider important?
• Will it let me experience the parts of work that have energized me before?
• Is this merely a change of environment, or a chance to go deeper into the work I want to do?
• Can I make this choice while sustaining my financial stability and my family's well-being?

I want to choose opportunities more consciously—not accept them automatically, but not let fear cause me to pass them up, either.

Final Reflection: The Life I Want to Build

I want a life of growth: one in which I take ownership of consequential problems and create real outcomes through products and execution.

I am at my best when I structure complex problems, find the critical bottleneck, and bring people and systems together to solve it. I feel most energized when I understand a customer's problem, put a solution into practice, and see the difference in metrics and customer experience.

I want to connect those strengths to meaningful business results and keep developing through the work itself. At the same time, the well-being of my family and the sustainability of my life are conditions I need to protect.

This is the Hedgehog I have identified for myself so far—not a final answer, but a direction to test and refine through the choices I make next.
