> And after being exposed, deciding they enjoy it, but would rather make a living elsewhere -- does that mean the hobby was a failure?

If they try a hobby for a while and give up on it because they don't enjoy it enough, then yes. That seems like a reasonable definition for "failure."

Nothing wrong with failing - in your career, hobbies, relationships, or whatever else. Sometimes EQ means recognizing that you should stop beating a dead horse.

Man I agree whole heartedly. Failure is a part of life, embrace it. There is no shame, you'll eventually find something you do enjoy.

There's more to life than a career.
