I think, therefore I am.

You cannot escape the responsibility of tomorrow by evading it today

Failure to prepare = preparing to fail

99% of genius comes from hard work, the remaining 1% comes from innate talent

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

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

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

Time is your friend, impulse is your enemy.

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

Try and do one thing each day that you would really rather not do.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

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

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

Tomorrow is worth more than yesterday but less than today.

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