The correct answer to this open question is the following.
According to Malcolm Gladwell's book "Outliers," some people are more successful than others because they possess three distinctive qualities that most people don't.
These qualities are Nature, Nurtured, and Luck. This means that some people have some particular skills from the day they are born. They have natural-born skills that they just develop or improve through life. Nurtured means that they are capable to know and learn other different skills so they can strengthen their capabilities when these are most needed. And finally, a little bit of luck, so the can have things their own way.
