With All I Know Now

If I could go back in time...to probably when I was four with all the knowledge i have now I would in an instant; wouldn't even think about it. Would I use my information of the future to stop events such as 9/11 from happening? I'm not exactly sure; I know I would use the information for selfish reasons, Acing all my tests in high school and getting into a great college. The possibilities are endless honestly.
