I started playing at your age and i've been playing for 4 years. Getting started is the hardest part, I play almost daily and a lot of times i get the feeling like i have still so much to learn. My advice is play in 15 - 20 mintues segments at least for an hour a day. And always watch other drummers, go to the music stores and just watch how the other people play, and ASK QUESTIONS!! Good luck.
