Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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

If you can understand just one thing thoroughly, then you will understand everything.

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

99% of failures come from people who have the habit of making excuses.

Tough times never last, but tough people do.

It doesn’t matter where you start, it matters how you end

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. 

You cannot start the next chapter of your life if you keep re-reading the last one.

Hard work - a two way street where you get exactly what you put in.

Don’t hang your targets after you’re done shooting.

Don’t be afraid to work hard and find out how good you can really be.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

In order to become better than anybody else you must first become better than yourself.

Practice like you’ve never won. Perform like you’ve never lost.
