  • 99: Selective Expansion: Growing Again, but Differently

    The freedom to pursue new possibilities after learning what is enough

    For much of my life, I believed that growth meant expansion.

    More opportunities, more responsibilities, more achievements, and more challenges. When I encountered something interesting, I wanted to try it. When I discovered a new possibility, I wanted to explore it.

    This approach served me well. It helped me build my career as a surgeon and researcher, develop new skills, and experience things I could never have imagined when I was younger.

    But expansion also came with a cost.

    There was always something more to accomplish. Another project, another responsibility, another goal. It was difficult to recognize when I had done enough.

    As I grew older, I gradually began questioning whether continuous expansion was the only way to grow.

    I realized that my life could be meaningful even without professional achievement. Family, physical training, writing, faith, and quiet moments of solitude offered different kinds of fulfillment.

    For a while, I wondered whether it was time to slow down and focus more on these other parts of life.

    But I also discovered something unexpected.

    I was not tired of creating, learning, or contributing. I still had energy, curiosity, experience, and abilities that I wanted to use. I still felt excited by new ideas and possibilities.

    I did not want to stop growing.

    Yet I did not want to return to my previous way of living either.

    This led me to a new concept: selective expansion.

    Selective expansion means continuing to create ambitious goals, pursue meaningful projects, and explore new possibilities—but choosing them carefully based on what truly matters.

    It is not about doing less.

    It is about knowing what deserves more.

    When I was younger, I often pursued opportunities because they were available, challenging, or might lead to greater achievement.

    Now I can ask different questions.

    Does this genuinely interest me? Will I enjoy the process, not just the outcome? Does it allow me to contribute something meaningful? Can I pursue it without sacrificing other important parts of my life?

    These questions require something that takes years to develop: knowing myself deeply enough to recognize what truly matters.

    I have learned that work is only one pillar of a rich life.

    Family, faith, physical health, creativity, relationships, and solitude are equally important parts of my larger landscape. No single pillar needs to become my entire identity.

    And because I am beginning to understand what is enough, I can pursue ambitious goals without needing them to define my worth.

    I can begin another research project without needing another prestigious achievement. I can improve my surgical skills without seeking everyone’s approval. I can write a book without needing it to become a bestseller.

    Once I choose a goal, I can still approach it with the same discipline and commitment that helped me during my earlier years. I can make plans, build daily routines, practice diligently, and work toward excellence.

    The effort does not have to become smaller. What changes is the reason for making that effort.

    And I can also try something new, discover that it is not right for me, and move on.

    Selection gives me the freedom both to begin and to stop.

    But knowing what matters is not sufficient. I also need to build systems that give those values a place in my daily life. Otherwise, even meaningful goals remain intentions.

    Perhaps this becomes especially important as we grow older.

    We often imagine aging as a gradual transition from expansion to maintenance and eventually contraction.

    But I am beginning to see another possibility.

    We can continue expanding throughout life, even after retirement. The scale and direction of our activities may change, but our curiosity, creativity, relationships, and capacity for growth can continue developing.

    I no longer need to become someone through achievement.

    But I still want to discover what I can create, contribute, and become.

    The difference is that I now know myself better.

    I know more clearly what matters.

    I am learning what is enough.

    And I understand that a rich life needs several pillars, not just one.

    The first expansion was about discovering what I could achieve.

    Selective expansion is about choosing what is worth pursuing.

    I do not need to keep doing more to remain young.

    I need to keep discovering something meaningful worth growing toward.

  • 98: Grow Together

    Sometimes Love Means Helping Someone Move Forward. Sometimes It Means Simply Being Beside Them.

    Last weekend, I ran a 5K race with my wife. It was her first race.

    For someone who has completed Ironman races, a 5K might seem like a small event. But this became one of the most meaningful running experiences of my life.

    I ran beside her throughout the race, encouraging her, helping her maintain her pace, and watching her discover how much she could accomplish. She pushed herself beyond what she might have imagined possible.

    Crossing the finish line together was wonderful.

    But afterward, I realized something deeper.

    Throughout our marriage, my wife has helped me countless times when I was struggling. During difficult periods in my professional life, when I felt disappointed, uncertain, or exhausted, she was always there.

    She could not solve my problems. She could not change the people or circumstances causing my struggles. Often, there was nothing she could actually do.

    But she stayed beside me.

    And that was enough.

    During the 5K, I helped her move forward. During my difficult times, she helped me simply by remaining beside me.

    I used to think that helping someone meant doing something—solving a problem, offering advice, creating an opportunity, or encouraging progress.

    But I am learning that there is another equally important way to help.

    Sometimes, we don’t need to change anything.

    We simply need to be present.

    Sometimes love means helping someone move forward. Sometimes love means staying beside them when they cannot move.

    Both are equally valuable.

    This realization has changed how I think about growing together.

    A long marriage does not mean two people always enjoy the same activities, share the same interests, or move at the same pace.

    My wife and I are different people. We enjoy different things. We each need our own time, interests, and space to grow.

    And over the decades, we have both changed.

    Our careers, family responsibilities, interests, and perspectives have evolved. The people we are today are not the same people who began our marriage.

    Yet we have continued growing together.

    Perhaps that is the real meaning of a lasting relationship.

    Growing together does not require growing in the same direction all the time. It requires continuing to make room for each other’s growth.

    Sometimes one person leads while the other follows. Sometimes one person discovers something new, and the other encourages them. Sometimes one person struggles, and the other simply remains nearby.

    The roles change throughout life.

    And something interesting happens through this process.

    When I helped my wife complete her first 5K, she grew through discovering her physical potential. But I also grew through experiencing the joy of helping her.

    When she supported me through difficult times, I grew through her presence. Perhaps she also grew through those experiences in ways I may not fully understand.

    Growth is not always an individual achievement. Sometimes it emerges from what two people experience together.

    I am beginning to understand that a rich marriage is not measured simply by how much time we spend together or how many activities we share.

    It is measured, in part, by whether we continue helping each other become who we are capable of becoming.

    Looking back, the most meaningful part of our 5K was not the finishing time.

    It was the experience of running beside someone who has stood beside me through so much of my life.

    We did not grow together because we always moved at the same pace.

    We grew together because, whenever one of us needed support, the other was willing to stay beside them.

    And after all these years, we are still discovering new ways to grow together.
