Procrastination is the thief of time and the enemy of success.

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

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

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

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

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.

The journey of a thousand miles begins with one step. 

Fall down seven times, stand up eight.

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

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

Failure to prepare = preparing to fail

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.

We all make mistakes. What matters is how we choose to move forwards from them.

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