When did you find your 'calling' in life?

Simple enough. At what point in your life did you find a career (or however you’d like to call it) that seemed right for you?

I’m almost 20, I’ve been going to Community college for 2 years now, and at no point in my life has there ever been a time that I thought “Wow, I know what I want to do with my life”, while my friends all seem to know at least generally what they’d like to do, so I’m wondering how common my situation is for other people across the internet.
