DON'T...

Don't try too hard to impress, you will have it all wrong. Don't spend what you can't afford just because you want to be accepted, you will not be able to sustain it. Don't fight a fight that isn't worth fighting, you will lose your cred. Don't burn your bridges, it will be impossible to go back. Don't prey on the weak to appear tough, you will be sorry when tables turn. I thought I should say that.
