Never underestimate the importance of small steps. small steps = big changes. 

Everything you want is on the other side of fear

It is never too late to become what you might have been

There are no bad mistakes in maths, only discoveries.

Instead of finding reasons why you can't, find reasons why you can.

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. 

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

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

A book a day keeps the stupidity away.

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

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

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

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

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

Fall down seven times, stand up eight.
