The age old argument of where talent comes from. It comes from both, that is the simple answer. But finding the right skill to nurture is the hardest part. Too often our (or other people's) wants and desires that are driven my societal norms overshadow skillaets and they are lost. That is not to say that an individual cannot just work hard at something they may not have an innate ability at and succeed in it. But without that hard work the innate ability is not enough, no matter what the talent is. Adaptability and conscious awareness of oneself are the key traits to develop in my opinion.
