also, I've yet to see anyone spending thousands of hours on productive practice and not get anywhere. Conversely, you can spend thousands of hours practicing a shitty golf swing and you're not going to get anywhere but an over-practiced shitty golf swing. Without correction and enforcing good technique and good habits at every practice, you're not going to get anywhere fast if at all.

Music is a bit of a poor example for application to "genius" actually because just like a golf swing much of it is in the practice of your gross and fine motor skills and good technique, which as we all know, if you don't rigorously practice good habits, you may as well not bother practicing at all because you're actively going in the wrong direction.
