There are no bad mistakes in maths, only discoveries.

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

We learn more from failure than we do from success.

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

There is no elevator to success, you have to take the stairs.

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

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

If you fail, next time fail better.

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

It is never too late to become what you might have been

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