Re: If I fail as a drummer? I can...?
I would say even if you are successful at drumming you might want to continue down other avenues that interest you. In the big picture music world, the more you can do, the better your chances to remain doing something musical, rather than have a completely different outside job and then your music. I know a guy who started out as a drummer, but now he's one of the better early-Elvis impersonators I've ever seen, he and his band work about 250 gigs a year. Not a bad drummer, either.
