The greatest glory in loving lies not in never falling, but in rising every time we fall.

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 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.

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

The master has failed more times than the beginner has even tried

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

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

Fall down seven times, stand up eight.

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

There are no bad mistakes in maths, only discoveries.

We learn more from failure than we do from success.

Failure to prepare = preparing to fail

Don’t practice until you get it right, practice until you can’t get it wrong.

The bad news is time flies, the good new is that you're the pilot.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.
