No one starts out on top. You have to work your way up.

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

Knowledge is of no value unless you put it into practice.

The greatest mistake we make is living in constant fear that we will make one.

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.

Our fixed mindset builds our cage, fear keeps us in it.

Failure to prepare = preparing to fail

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

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

The journey of a thousand miles begins with one step.

There are no bad mistakes in maths, only discoveries.

We learn more from failure than we do from success.
