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

I think, therefore I am.

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

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

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. 

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

Don’t hang your targets after you’re done shooting.

The power of reflection is the most powerful skill you’ll learn.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

The temptation to quit will be the greatest when you are about to succeed

There is no elevator to success, you have to take the stairs.

Success is a journey, not a destination.

Failure is not the opposite of success, it is part of the success.

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

Try and do one thing each day that you would really rather not do.
