I once wrote that studying for twelve to fourteen hours a day had become routine. At the time, I treated endurance as proof. The more work I could carry, the more serious and capable I felt. The work taught me what I could do. It could not tell me what I was worth, though I often asked it to. I no longer need to organize my life around proving that I belong.
When I was a junior engineer, raising my hand for nearly everything helped me learn quickly. I wanted to be useful, but I also wanted to be seen as useful. Because I usually delivered, the habit looked like a strength. Yes became a reflex, and I considered the cost only after I had committed. There is now room between a request and my answer. I can pause and ask whether the work should be done, whether I am the right person to do it, and what I would have to set aside. Sometimes I accept the work. Sometimes I push back or suggest another path. Either way, the answer no longer has to prove that I belong.
My ambition is no longer limited to what I can accomplish myself. I still want to solve difficult problems and build systems that remain useful beyond my involvement. I also want to work in ways that make room for the judgment of other engineers, especially when it differs from mine. Much of this happens in ordinary conversation: talking through a design or technical problem and making time for us to teach one another.
The same need to prove myself shaped how I handled disagreement. When being right was tied to belonging, criticism could feel larger than the idea under discussion. I can be wrong without becoming a fraud, and I can revise a belief without diminishing myself. As people have come to trust my judgment, my words can carry farther than my own work. That gives me more reason to listen when evidence or another person challenges me.
That openness changes how I meet ideas outside work. A novel can change me before I can say what it has taught me. I can take a philosophy seriously without accepting it, and I can try to understand another person’s convictions without sharing them. Influence is not assent. I think of identity as a working model: stable enough to live by, but open to revision when it no longer fits reality. I still care about working hard and being capable. What has changed is what I ask the work to mean. Before I say yes, I can ask whether this is where my time and effort belong.
