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

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

You cannot escape the responsibility of tomorrow by evading it today

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. 

A book a day keeps the stupidity away.

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

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

You can hire a tutor but you can't hire someone to practice for you.

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

It is never too late to turn an unproductive day into a productive one.

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

There are no bad mistakes in maths, only discoveries.

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