I think, therefore I am.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Everything you want is on the other side of fear

There is no elevator to success, you have to take the stairs.

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

Life is full of opportunities. With every opportunity that is missed, another one is born.

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

Hard work beats talent when talent doesn't work hard.

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.

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

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.

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

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

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

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