The master has failed more times than the beginner has even tried

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. 

Success is a journey, not a destination.

The journey of a thousand miles begins with one step.

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.

I have not failed, I've just found 10,000 ways that won't work.

You cannot escape the responsibility of tomorrow by evading it today

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

There are no bad mistakes in maths, only discoveries.

MATHS = Mistakes Allow Thinking To Happen

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

Everything you want is on the other side of fear

Life is full of opportunities. With every opportunity that is missed, another one is born.
