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

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

Success is a journey, not a destination.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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

Try and do one thing each day that you would really rather not do.

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

No one starts out on top. You have to work your way up.

The greatest enemy to human potential is your comfort zone

Time is your friend, impulse is your enemy.

You can have results or excuses, not both

The easiest person to deceive is yourself.
