I have obviously improved a ton since i first started but i feel like it is almost impossible to get to the level of professionals, especially metal players that can play rapidly and with clarity.

I have obviously improved a ton since i first started but i feel like it is almost impossible to get to the level of professionals, especially metal players that can play rapidly and with clarity. Is the ability to learn guitar easily and well something you are born with, or can it be achieved through tons of practice. I practice almost daily for hours, but i feel like i reached a wall when it comes to some techniques like sweep picking and rapid playing.
