There are no bad mistakes in maths, only discoveries.

We learn more from failure than we do from success.

Failure is NOT your destiny. Failure is the key to success.

The journey of a thousand miles begins with one step.

The temptation to quit will be the greatest when you are about to succeed

Success is the sum of small repeated efforts, day in and day out.

Pure mathematics is in its way, the poetry of logical ideas.

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 cannot escape the responsibility of tomorrow by evading it today

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

Everything you want is on the other side of fear

Fall down seven times, stand up eight.

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

If you really want something you’ll find a way. If you don’t you’ll find an excuse.
