i have some theory about rules in life:
- be grateful for life everyday. God is always number one.
- dont trust people easily.
- dont cry just because u want attention and pity. If u want to do it, go to ur room and lock it
- act strong even if u are broken on the inside
- dont care too much over silly things
- be smart!
- brain before heart
- stay away from fake and hypocritical people
- be yourself
- dont hold up your feelings. say what u have to say
- be independent 
- dont hesitate to leave untrustworthy people or u will waste your time
- dont waste your time
- have goals in life
- wake up, do everything that makes u closer to ur goals
- respect your elders
- fix every problems in your family and u can conquer the world
- smile
- last but not least, if life beat u down, get up and say "u hit like a b*tch!" and go on.
