I think, therefore I am.

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

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

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

The master has failed more times than the beginner has even tried

We learn more from failure than we do from success.

You can have results or excuses, not both

Fall down seven times, stand up eight.

Don’t practice until you get it right, practice until you can’t get it wrong.

Procrastination is the thief of time and the enemy of success.

Life is full of opportunities. With every opportunity that is missed, another one is born.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

Tough times never last, but tough people do.
