It is never too late to become what you might have been

You cannot start the next chapter of your life if you keep re-reading the last one.

Practice like you’ve never won. Perform like you’ve never lost.

Your attitude is everything. Pick a good one.

I think, therefore I am.

Time is your friend, impulse is your enemy.

If you can understand just one thing thoroughly, then you will understand everything.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.
