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

The journey of a thousand miles begins with one step. 

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

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

Success is a journey, not a destination.

Skills are built not born.

It is never too late to turn an unproductive day into a productive one.

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. The most powerful warriors are patience and time.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

Lose an hour in the morning and you will spend all day looking for it.

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

It always seems impossible until it's done.

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.
