If you're asking your kids to exercise, then you better do it, too. Practice what you preach.

If you want to take your mission in life to the next level, if you're stuck and you don't know how to rise, don't look outside yourself. Look inside. Don't let your fears keep you mired in the crowd. Abolish your fears and raise your commitment level to the point of no return, and I guarantee you that the Champion Within will burst forth to propel you toward victory.

I still have nightmares about taking tests.

To me, the definition of focus is knowing exactly where you want to be today, next week, next month, next year, then never deviating from your plan. Once you can see, touch and feel your objective, all you have to do is pull back and put all your strength behind it, and you'll hit your target every time.

The most challenging aspect of the decathlon is not the events themselves, but how you train to become the best 100-meter runner you are on the same day that you're the best 1,500-meter runner.

If I was lying on my deathbed and I had kept this secret and never ever did anything about it, I would be lying there saying, 'You just blew your entire life.'

I'm the type of guy who fails and fails and fails, and then, as if failure has become sick of him, succeeds.
