That's an easy question...
maybe not Practice till you're satisfied with the amount of practice for the day.
+1 Couldn't have said it better.Wanting to be the top drummer...sounds like you have your priorities misplaced. You are putting yourself before the music. The music comes first. If you play it so awesomely, then others will notice, and your (misplaced) goal will start to take shape.
Practicing by yourself means almost nothing until you start playing with others. That's when the real growth starts. If you want to be a top drummer, and you haven't played with anyone yet, you have a long long way to go. You make it sound so easy. Oh I want to be a top drummer. It doesn't work like that.
