What if I'm successful in a field I never really chose?

You arrived here honestly. Pragmatism and inertia are not crimes. They are how most people end up where they are, taking the next reasonable step and then the next, until one day you look up and find you are senior in a place you never deliberately picked. The success is real. So is the quiet feeling that something is missing. Both things are true at once. It helps to separate two questions you may be blending together. One is whether the meaning is missing from this field, or from how you are spending yourself inside it. Sometimes the field is genuinely wrong. Just as often, the same skills could be pointed at work that matters more to you, without throwing everything away. You do not have to make a dramatic decision this month. Instead, get specific about what meaning would even look like for you, because right now it is a vague ache. Write down two or three moments in your career that felt genuinely worthwhile. Look for what they had in common. That pattern is your compass, and you can steer toward it slowly.
