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

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. 

Run in the morning before your body figures out what you're doing

Everything you want is on the other side of fear

Failure to prepare = preparing to fail

99% of genius comes from hard work, the remaining 1% comes from innate talent

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

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

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

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

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

Fall down seven times, stand up eight.

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
