You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

We are all maths people : step 1 - do maths and step 2 - be a person. 

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

The easiest person to deceive is yourself.

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

You cannot escape the responsibility of tomorrow by evading it today

Your attitude is everything. Pick a good one.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

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.

Don't fear failure, fear being in the same exact same place next year as you are now.

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

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

Tomorrow is worth more than yesterday but less than today.

Our fixed mindset builds our cage, fear keeps us in it.

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