The expectation of a settled answer early comes from watching the few people who knew at fifteen and got asked about it constantly ever since. Most lives do not run that way. Not knowing at nineteen is the ordinary condition, and treating it as a personal defect adds panic to something that only needed time.

Swap the question of what you will do for the question of what you want more of this year. Follow that answer with real hours rather than more research. Directions get found by trying things, almost never by thinking harder while sitting still.
