I spent more than 7 years on a failed company. And this was in my 30s, let alone 20s. My friends around me are all wealthy with paid off houses. I am not. But I traveled the earth, had crazy adventures, and was able the parlay my experience into one of the most coveted jobs on earth and am now nearly financially caught up with my friends after another 5 years. It was a struggle, but it was worth it, and I have no regrets.
