There are many people who could be Olympic champions. All-Americans who have never tried. I'd estimate more than 5 million people could have beaten me in the pole vault the years I won it... at least 5 million. Men that were stronger, bigger and faster than I was could have done it, but they never picked up a pole, never made the feeble effort to pick their legs off the ground trying to get over the bar.

If you want to be the person you ought to be, you've got to welcome competition.

You are what you think. You are what you go for. You are what you do! You are what you think you are.

One of the great lessons I've learned in athletics is that you've got to discipline your life. No matter how good you may be, you've got to be willing to cut out of your life those things that keep you from going to the top.

The health of our home planet and the survival of our species will only be secured through the use of space resources and the expansion of Earth's economic sphere to the Moon and beyond. Creating an off-Earth economy and multi-planet civilization will safeguard the long term prospects of humanity.

You are what you think you are.
