A hero is no braver than an ordinary man, but he is braver five minutes longer.

Just stick with it, what seems hard now will one day be your warm up.

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

I can is 100 times more important than IQ.

Time is your friend, impulse is your enemy.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

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

There are no bad mistakes in maths, only discoveries.

We learn more from failure than we do from success.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

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

You cannot escape the responsibility of tomorrow by evading it today

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

Knowledge is of no value unless you put it into practice.

I think, therefore I am.
