At a seminar at TED with some of the most brilliant minds, Tony Robbins inspires even the best of them. He doesn’t motivate them but he piques their mind to know why certain people are successful. Robbins says it is all about not what you do, but why you do it. He says it is all about purpose and clarity. We all make decisions in our life and we all run into hurdles. Psychological strength is the difference in what makes certain people successful through their decisions to fight through those hurdles and obstacles to reach the ultimate goal.
