In order to become better than anybody else you must first become better than yourself.

Everything you want is on the other side of fear

You can have results or excuses, not both

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

The temptation to quit will be the greatest when you are about to succeed

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

The greatest mistake we make is living in constant fear that we will make one.
