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

Failure to prepare = preparing to fail

Skills are built not born.

Hard work - a two way street where you get exactly what you put in.

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. 

The greatest glory in loving lies not in never falling, but in rising every time we fall.

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

Just stick with it, what seems hard now will one day be your warm up.

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

The bad news is time flies, the good new is that you're the pilot.

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

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

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

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.

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