Life is sometimes unfair, unreasonable or unjust. But how you handle these situations is one of the things that separates successful people from the unsuccessful, says self-made multimillionaire and serial entrepreneur Scott Galloway.
"You will know failure.... You will be treat treated unfairly at work. You will get fired. Your businesses will fail," Galloway tells CNBC Make It. "Before the age of 40, I had businesses go bankrupt, I had a marriage fail and I lost the only person that to that moment I knew loved me — my mother.
"But for me, these were setbacks not barriers," says Galloway, who sold his company L2, Inc., reportedly for over $130 million.
"It's easy to hold a grudge, it's easy to have a difficult time not getting over an injustice," says Galloway. But "your ability to move on and not hold grudges and not hold anger inside such that it starts to almost burn your veins like acid is a key" to being successful in life, Galloway says.
"Success is a function of your resilience over your failure."
Be upset — that's natural, says Galloway, "but then get up, dust your pants off and move on, recognizing that failure is part of the arc of success." Things like exercise, spirituality or something as simple as talking about what made you angry can help you move on, says Galloway.
