I think the desire for success is often the initial driving force for people who turn out to be “hyper-successful”, such as Tony Robbins. However, I think there comes a point when they transition to derive their satisfaction/meaning from other things, most notably contribution and legacy. Tony Robbins points out that fulfillment comes from the feeling that your life matters – that you are needed by other people. The other day I saw a video in which another super-successful person, Ray Dalio, said that this desire to mentor others was the reason for writing his book Principles.
