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

If you fail, next time fail better.

The wise person knows that no answer is also an answer

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

Success is a journey, not a destination.

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

Lose an hour in the morning and you will spend all day looking for it.

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

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

We learn more from failure than we do from success.

The temptation to quit will be the greatest when you are about to succeed

The bad news is time flies, the good new is that you're the pilot.

He who has begun his task is half-way done. Have the courage to begin!

Success can never happen without the journey (struggle).
