If I could live my life differently

If I could go back in time, what would I change about my life? I would have gotten rid of my ex boyfriend sooner. I'd have gone to the gym more. I'd probably be in California studying theatre right now at UC Irvine. I would have gotten the Juilliard Internship I wanted so badly a few years ago. I'd have stayed in school so that right now I'd be studying for my master's instead of my bachelors. I'd have focused more in high school and more in college so I could get better grades. I would probably have started being nicer to people at an earlier age so that I might possibly have more friends, although I probably wouldn't have more friends anyway since I can tell when people are being fake and it's something I hate more than anything else in this world. My life would be completely different if I'd had done things properly, but then I also wouldn't have the life knowledge I now have since I have experiences now that I sometimes wish I could connect.
