Take away quote from the article:

"My hypothesis is that most children are emotionally damaged by [growing up in a dysfunctional family]. But a small percentage, whose brain chemistry and wiring is set for resilience, come out of this with a compulsive, relentless and tenacious drive to succeed. They have learned to function in a permanent state of chaos. And they have channeled all this into whatever activity they could find outside of their home – sports, business, or …entrepreneurship."
