Looks get you far on a certain extent, if you don't know what you're doing or have know real knowledge, it's safe to say you wont ever get a good job. But really looks are good to have, but if you want to do anything with your life then have some sort of knowledge to back yourself up, I'm sure no one wants to be working at wal-mart or mcdonalds.
Don't argue with idiots because they will drag you down to their level and then beat you with experience.
I don't think you need to be pretty or handsome to go far in life like some people think. If you're neither, you would just need to cross a couple of things off of your list of career choices. O-o'
