Well I just freed myself of the mess of high school (I'm a freshman in college) and I'm going to be sorta blunt about this....
Once I was out of high school I looked back and wanted to hit my head for every time I worried about what other people thought of me. High school is very shallow and very 'clique'-ish.
Don't get me wrong, I enjoyed it, but real life is not at all like high school. In addition to that...I wouldn't be too worried about people not liking you anyway. Did you know that over 96% of high schoolers are always worrying about themselves? As such rarely does anyone really notice if you mess up big time, unless you make a big deal over it. (I don't know if 96% is the exact statistic anymore. That's what I was told my sophomore year at any rate.)
To top off this stupendous rant I'm going to be a Bible banger. We, as people, should really worry about pleasing God the most. If other people don't like it, tough. And He loves you more than anyone else possibly could.
