You started with this song??!! Wow. I've hurt myself air-drumming it
Much like Dieter said earlier about himself, i was also obsessed with getting better and practicing drumming daily. My family had moved around a lot and it was tough being 14 yrs old without any friends. Get home from school, put on the headphones and scan the FM radio dial and learn timing and basic stuff. Once i felt i could outplay most of the simpleton drummers who were on rock/pop radio at the time....I started trying to play along with the big boys, Peart and Bonham.
The cool thing about all of this is that by becoming a drummer i met a lot of other musicians and made some close friends, which saved me as a young, miserable, loner teen.
I don't know about you guys and your instrument(s) of choice, but i just found the drums a natural instrument for me. There have been long gaps of not playing the drums and yet i can pick it right back up every time.
Learning to play guitar was always hard work for me...and still is.
