The article speaks of success in terms of talent plus hard work.<p>I posit that perhaps Social factors are the third key contributor to outcomes.<p>e.g. in simple terms: imagine genius twins, separated at birth, one raised well in a functional family and taught a work ethic and counselled on his life's path, becoming popular and charismatic among his peers, and the other in a broken family with little guidance or resources, socially shunned, with life an endless lesson about lack ... and it's arguable that such factors play as much, if not more, part in outcomes than anything the individual can personally do or decide, /within the limitations of their own experience/.<p>At least, until later in life, when hindsight and context allow more objective evaluations.
