"Winners, leaders, masters -- people with personal power -- all understand that if you try something and do not get the outcome you want, it's simply feedback. You use that information to make finer distinctions about what you need to do to produce the results you desire.... Sometimes we learn from our mistakes, sometimes from the mistakes of others. Take a minute to reflect on the five greatest so-called 'failures' of your life. What did you learn from these experiences? Chances are they were some of the most valuable lessons you've learned in your life."  Tony Robbins
