Cool that you mention a sport. I got so caught up in learning an instrument that I never even gave a thought to it.
I think just drumming all day for 2 years is going to take the fun out of it for me. I'd love to practice and perfect my snooker and pool skills along the way. Until then, I can only drool while watching Ronnie O'Sullivan score 147s like I take a dump.
Ahh instruments. I once pursued that path but gave up awhile ago. I tried learning piano and it just didn't work out. I didn't set up a good enough routine / schedule. I should have came up with piano dallies for myself to complete or something. haha.
