I think that to be inspired and improve, you have to reach for the top. Wether you get there or not is moot, but it has nothing to do with realism.
As one Bass Chatter put it 'you don't need to learn how to slap, to play Brown Sugar'. Had I thought that when I started I would not have bothered with those Billy Sheehan & Stu Hamm tuition videos.
The only thing I knew I wanted from my playing when I started, was fun.
