I can is 100 times more important than IQ.

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

If you fail, next time fail better.

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

The greatest glory in loving lies not in never falling, but in rising every time we fall.

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

Never underestimate the importance of small steps. small steps = big changes. 

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

There are no bad mistakes in maths, only discoveries.

Mistakes have the power to turn you into something better than you were before.

Failure is not the opposite of success, it is part of the success.

It always seems impossible until it's done.

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

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

You cannot escape the responsibility of tomorrow by evading it today
