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. 

I think, therefore I am.

We learn more from failure than we do from success.

It always seems impossible until it's done.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

The journey of a thousand miles begins with one step. 

He who has begun his task is half-way done. Have the courage to begin!

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

If you fail, next time fail better.

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

The road to success is like a staircase. If you want to succeed, double your failure rate

The greatest enemy to human potential is your comfort zone

We are all maths people : step 1 - do maths and step 2 - be a person. 

Success is a journey, not a destination.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.
