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

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

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.

Success is not final and failure is not fatal. It is the courage to continue that counts.

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

Hard work - a two way street where you get exactly what you put in.

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

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

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

It always seems impossible until it's done.

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

We learn more from failure than we do from success.

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

Start, struggle, fail, fix and learn. Repeat.

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