I stopped working to write this comment--that's how important it is to me that you know this is a belief that will only hold you back.
I could cite any one of thousands of articles that talk about dropouts who made it, but I suspect you know about those articles and it hasn't affected your belief.
So I'll just say this: If I had graduated with a degree, I would have never been able to bootstrap a tech company when I was 20 and sell it for over a million dollars when I was 26.
Don't look at yourself through the eyes of others, because you'll always find yourself wanting. I'm sitting here about to launch my new company (we're doing final testing of our new website right now.) I have no idea whether our site (which is kind of wacky) will convert. I don't know if we'll get any sales. And I've got everything riding on this company--I've put all my chips in.
There's enough in this world that will kick your ass. People haven't believed in my companies for the past 13 years I've been running them. People have laughed in my face, investors have turned me down over and over again, customers have quit, money has been lost (and, on a brighter note, much money has been made!)
Sometimes the only thing you can count on is your internal belief that you WILL make it, no matter what. That's what got me through my last company during its darkest hours. That's what's getting me through now. Enough people will throw shit in your face. Don't be one of them. You are better than that.
The world is full of possibilities. Don't count yourself out. Jennifer sure didn't. ;)
