Perfectionism isn’t healthy. Yet, here’s the reality based on my nearly 25 years in the trenches with the titans of industry, world-changers, NBA superstars and music icons: the great ones are all obsessive. They cannot bear being mediocre. They cannot live stagnating at ordinary. They have uncontainable hunger to exploit their potential, bring on mastery and turn their entire field on its head. 

Mahatma Gandhi said it beautifully. "One cannot do right in one area whilst he is occupied and doing the wrong in another area."

So please remember - the way you do one thing defines the way you do everything.
