Most Helpful Guy
I would advise against Plastic Surgery unless you have some deformity (for lack of better word) if you honestly "hate your life" because your nose is ugly, broken, messed up, off to the side (for example) then sure! By all means, if it makes you a happier person, then you should do whatever you feel like doing in the long run.
I don't know of any other physical tricks to change your appearance.
Good luck!, I'm sure you're perfectly fine though. :)
