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

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

We all have two lives. The second begins when we realise we only have one. 

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

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

The easiest person to deceive is yourself.

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

There are no bad mistakes in maths, only discoveries.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

Everything you want is on the other side of fear

You can hire a tutor but you can't hire someone to practice for you.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

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

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