I wont be the best, I just want to get better. The best is something particular of that moment, you can't be the best because a minute after reaching it a new thing comes out or another problem will be face the earth and other people may figure it out better than you.

To me, it's more importante to focus on be better than you're now. You can measure this easily by seeing real world examples of what you want to achieve, then, force you into a method to improve your skills until you feel you're mastering. That could be more rewarding than feeling to be "the best".
