Tips and Pointers Anyone? :)

I am actually a senior in high school and i really want to make a differnce in my life! I want to graduate and also be celebrating a change in my life! I want to graduate and i want my classmates to see the change i made for myself. so what i am trying to get at here is, i just started and i was wondering if anyone can share their stories and what they did to change their lives! I am also open to friend requests because i sure know i don't want to do this alone! (: thanks everyone!
