I fly airplanes. More specifically, the Boeing 737. It's a fun job and I make decent money doing it, but it's very hard and expensive to get into. Student loans are in the $150,000 - $200,000 range and many people end up being a completely qualified airline pilot with $150k debt and working in a supermarket because it's so hard to get a job. Usually, I end up with 3 days off in a week which gives me a lot of free time. I also have a decent amount of vacation days in a year which allows me to travel to interesting places. The downside is that it's hard to get very specific and popular times off.
Losers always whine about their best. Winners go home and fuck the prom queen.
