Yes, there are naturals. We look at some and say, no wonder they're good, just look at their work ethic. But some were born geniuses to begin with, and that natural ability gives them incentive to tirelessly capitalize on it. Hence, genius first, work ethic next.
There are those who are very good who are pointed out as naturals but they're just hard and smart workers. The existence of one doesn't negate the existence of the other..
And, while we're on the subject, there are those who are born without certain skills and aptitude, no matter how hard they try.
I've worked with too many naturals, as well as been around those who, no matter how hard they try, just cannot get it.
