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. 

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

Tough times never last, but tough people do.

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

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

Fall down seven times, stand up eight.

We learn more from failure than we do from success.

The greatest enemy to human potential is your comfort zone

You cannot escape the responsibility of tomorrow by evading it today

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

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

There are no bad mistakes in maths, only discoveries.

Success is a journey, not a destination.

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

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