Fatigue makes cowards of us all.
Success demands singleness of purpose.
Praise in public criticize in private.
If you can accept losing, you can't win.
Mental toughness is essential to success.
Winners never quit and quitters never win.
If you can't accept losing, you can't win.
Once you learn to quit, it becomes a habit.
In great attempts it is glorious even to fail.
Winning isn't everything, it's the only thing.
