My first trip I'd go back and make sure I did all of my homework, because stupid decisions get made by indecision, so I think if I went back in time and socked myself every time past me missed an assignment, it'd be all good, and I wouldn't be stressing about college.

As a more frivolous yet esteeming trip back in time, I'd break up with the girl I dated for two years to avoid the heartbreak she was gonna bring me, and get with the girl who works with me currently but no longer digs me since I lost my chance by ignoring her for a year at the sake of keeping the present girl. It's a dumb situation, and I'm honestly not sure if I'd be any happier or wiser if things changed, but hey, it's my hypothetical timeline, so whatever.
