Keep as many options open for as long as possible is a good rule.
My favorite rule is 'you must find work that satisfies your values' particularly when one has lots of choices. For example, I think I have a bit of a 'natural gift' for writing advertising. I used to watch 'Bewitched' and be fascinated with what Darin Stevens did for a living. Dr. Suess started off in the Advertising Business. But propping up consumer culture just doesn't fit my values, so I didn't take that path.
Best Wishes,
