Replying to Development vs. Raw Skill

I was talking with a friend of mine earlier and he said "yeah, he just doesn't have the balance to be a good park skier, he just has no fear." Do you think you are able to mold yourself into an improved park skier by putting in the work, falling and pushing yourself to progress, or are you seemingly born with the balance, coordination, and whatnot that you need to become a good park skier, which allows you the ability to develop much better and faster?
