Golfer Arnold Palmer has won hundreds of trophies but apparently he never flaunts these. I have read that in his office is only one trophy on display. It is a small cup he received at his first professional win at the Canadian Open in 1955. And on his office wall is a lone framed plaque which reads:

If you think you are beaten, you are.
If you think you dare not, you don't.
If you'd like to win but think you can't, it's almost certain you won't.
Life's battles don't always go to the stronger or faster man,
But sooner or later, the man who wins is the man who thinks he can.

As the Bible says, "As a man thinks in his heart, so is he" (Proverbs 23:7).
