I think, therefore I am.

Go as far as you can see, when you get there, you’ll be able to see further

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

Everything you want is on the other side of fear

Success is not final, failure is not fatal.  It is the courage to continue that counts.

Don't fear failure, fear being in the same exact same place next year as you are now.

Failure is not the opposite of success, it is part of the success.

Mistakes have the power to turn you into something better than you were before.

Don’t hang your targets after you’re done shooting.

The easiest person to deceive is yourself.
