Success can never happen without the journey (struggle).

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

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

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

It always seems impossible until it's done.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

Your limitation - its only your imagination.

Instead of finding reasons why you can't, find reasons why you can.

Time is your friend, impulse is your enemy.

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

Failure to prepare = preparing to fail

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

The greatest enemy to human potential is your comfort zone

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

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