Shane the nest 7 years will be the most fun of your entire life. Make sure you enjoy it. Break as many nonsensical rules you can, stay out late with your homies and hook up with as many chicky babes as you can. The only other piece of advice i'll give is to respect everyone around you and don't hurt anyone when ur on your teenagerly rampages.
Congrates, it was only yesterday I was 13 :lol: ...and now I'm 38. You won't believe how fast it disappears! Hang on to it and don't be so eager to get older
