Things I’ve Learned What I wish I knew at 18… 1. College is mostly a scam I’m glad I went to college, because I wanted to work on Wall Street. But today, I wouldn’t waste $300,000 on it, and I wouldn’t want to work in banking. Instead, I’d load up on college credits during high school, go to a school like the University of Texas to have fun, graduate in 3 years debt-free, and travel around the world for a year.
