"If you view life at 50 the same as you did at 20 - you have wasted 30 years of your life." - Muhamad Ali




I think that is true. When you are 50 you should have gained some experience from when you were 20 and if you havent then it has been a waste of time and a waste of 30 years. I believe it is saying "Live your life to the fullest" in a way.
