Why this is significant

Ever since i read this CNN article I have been on a forwarding spree. Seemingly displaying excitement beyond what one would usually reserve for studies such as these which are usually a dime a dozen. For every study that plumps for one intution, there is one that goes the opposite way. Starting with this healthy dose of cynisism, I will go on to illustrate why this study has me hopping.
The premise of this article for those who would rather not click out haha, is that greatness is a function of hardwork.(hardwork thats directed at generating continuous improvement).
Now this might be hard for most of us to accept , are'nt certain people born to greatness? Surely we have seen it in our own midst, some kids pick up things quickly while others struggle. There is one Tiger Woods and then there are the rest. Surely hardwork can achieve only so much.
It is these very statements that seem to be true , that the study debunks.
At birth we start a proces of learning that ebbs and flows with time. And ends only at death.
When we start something new , the learning always is fast in the beginning and then tapers off. Some of us keep at it while most of us are satisfied/bored enough not to.
No prizes for guessing who gets to be the best.
Now motivation to keep at it is something that we are either born with or not. But I can live with that, what I can't live with is somebody being better than me on the basis of birth.
