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

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

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.

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

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

A book a day keeps the stupidity away.

It doesn’t matter where you start, it matters how you end

Everything you want is on the other side of fear

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

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

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Start, struggle, fail, fix and learn. Repeat.

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

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

If you want to succeed, double your failure rate.
