Fail Forward. Fail Often. "Failure is a massive part of being able to be successful".
Dalio's views on mistakes sound very much like Neil Gaiman's view on mistakes, one written by a story teller (I take a look at Gaiman's commencement address extolling mistakes in an earlier post) and the other written by an "investor-philosopher".
Will Smith probably has a larger following than Ray though...
If you'd like to feel inspired by commencement addresses and life lessons try: Neil Gaiman on making wonderful, fabulous, brilliant mistakes; or Nassim Taleb's commencement address; or JK Rowling on the benefits of failure. Or Charlie Munger on always inverting; Sheryl Sandberg on grief, resilience and gratitude or investor Ray Dalio on Principles.
