I want to believe that the way you find the right career is by trying lots of different things. But so far none of those things are letting me try them. I really do think that part of it might be that I am so criminally bad at selling myself.
The older I get, the more I believe that the idea of "finding the right career" is a myth. Sure, there are people like Pedro or August who go to school for a thing, and then do that thing. But the vast majority of people I know have done a whole bunch of different things, sometimes related and sometimes not, and eventually either drifted into something they enjoy and stuck there or made an active decision to pursue some kind of schooling based on what they'd learned from the series of random jobs they'd already done.
I mean, I'm not old and I have had long periods of deliberate unemployment, but in the last fifteen years I've been a waitress, an administrative assistant (three times), a retail clerk (twice), a ballroom dance instructor, a blackjack dealer, a fast food grunt, a grad student, a freelance writer, and a stay-at-home mom. I'm really happy with my current job and I can't think of anything I'd rather be doing at this point in my life, but this job isn't going to fit forever and I have no problem moving on when the time comes.
On a slightly tangential note, what I know about myself now that I didn't in college is that I don't like doing the same thing every day, I prefer to work independently instead of collaboratively, and autonomy is extremely important to me -- which is why the thing I went to college for (secondary education) would have been a very, very poor fit. I am SO glad I didn't get a teaching fellowship.
