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

It always seems impossible until it's done.

Do what you have always done and you will always be what you have always been

If you want to succeed, double your failure rate.

Failure is NOT your destiny. Failure is the key to success.

The easiest person to deceive is yourself.

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

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

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

I have not failed, I've just found 10,000 ways that won't work.

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

Don’t hang your targets after you’re done shooting.
