If you're going to use that definition, then everything becomes an exit... Work 12 months to make $2500, less than you would make in 3 months working part time job at Wal-Mart, must be an exit. Flip a used car for a $300 profit, another exit! Put up a garage sale, exit again!
Seriously, it's a lesson learned, experience gained. Not an exit.
Edit: to the downvoters, when you use the words "hate", "love", "epic" to validate some relatively-minor (to actual meaning) event or emotion, you're taking meaning out of that word ... in some cases just to feed that meaning to your ego.
An exit is an exit. He made something, and sold it FOR PROFIT in 6 months, while being in college. Pretty impressive.
