1. "Wherever you see a successful business, someone once made a courageous decision." Peter Drucker

2. "I found every single successful person I've ever spoken to had a turning point.

5. "On an important decision one rarely has 100% of the information needed for a good decision no matter how much one spends or how long one waits. And, if one waits too long, he has a different problem and has to start all over. This is the terrible dilemma of the hesitant decision maker." Robert K. Greenleaf

6. "The greatest mistake you can make in life is to be continually fearing that you will make one.--Elbert Hubbard We need to accept that we won't always make the right decisions, that we'll screw up royally sometimes--understanding that failure is not the opposite of success, it's part of success."

19. "Stay committed to your decisions, but stay flexible in your approach." Tony Robbins

20. "Just really, really believe in what you're trying to do. Don't let people alter that. Let people advise you and lead you down paths to make smart business decisions.
