There are no bad mistakes in maths, only discoveries.

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

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

Hope might be a good breakfast, but it makes a very poor dinner

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

If you fail, next time fail better.

Your attitude is everything. Pick a good one.

Tomorrow is worth more than yesterday but less than today.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

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

You cannot escape the responsibility of tomorrow by evading it today

We learn more from failure than we do from success.

Patience is when you’re supposed to get mad, but you choose to understand

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

Don’t practice until you get it right, practice until you can’t get it wrong.
