Tomorrow is worth more than yesterday but less than today.

We learn more from failure than we do from success.

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

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

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

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

Fall down seven times, stand up eight.

Pure mathematics is in its way, the poetry of logical ideas.

If you fail, next time fail better.

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

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

Your limitation - its only your imagination.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

You can be shown the path, but only you can make the first step.
