Undecided Question

Could someone give me some good beauty tips?

So when I was younger, everyone always told me how pretty I was. I didn't have the prettiest friends, so usually I felt pretty good about myself. Now, all my friends are prettier than me, and I feel really sad about it. I'm happy for them, but I just wish I could make myself feel better about myself. I have lots of freckles, which sometimes makes my skin look unclear, when actually, I have pretty good skin. I'll be getting braces really soon, so my teeth aren't really a problem, but I think I'm going to get plastic surgery on my nose, because whenever I look in the mirror, it is the first thing I notice. It is HUGE! And I hate it… I would add a picture, but I don't have one at hand right now. Please give me some tips on clearer skin, and tips on how to prepare for a nose job. That'd be great thanks :)
