Tough times never last, but tough people do.

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

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

I can is 100 times more important than IQ.

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

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

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

There are no bad mistakes in maths, only discoveries.

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

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.

You can be shown the path, but only you can make the first step.

We learn more from failure than we do from success.

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. 

Nobody said it’d be easy, they just promised it would be worth it.

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