"Get busy livin' or get busy dyin'". That was from the movie The Shawshank Redemption right before Andy broke out of prison. I try and live my life by that saying. Live life to the fullest and don't put off things off because you never truely know how much time you have on this earth.
Another great person who I think has a ton of insight on being sucessfull is Dan Gable. I wrestled for most of my life and most of my family is from Iowa. I spent my summers running up and down the stairs of Carver Hawkeye arena and training with Dan and a bunch of other guys at some olympic development camps. Just listening to that guy's philosophy on life and how to remain focused is amazing. He just did things so simple and it made so much sense. We spend too much time looking for short cuts around things. If we spent as much time and energy that we do looking for the easy way out on our goals, we would reach them that much faster and with better results. You plan way ahead, stick to your plans, and work harder than you thought possible and you can do anything. In 1972 at the olympics, Dan Gable won the gold and not one person scored a single point on him. Thats amazing to me and knowing what I know now about the way he thinks and lives his life, anything is possible if you stick with it.
