Failure to prepare = preparing to fail

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

Time is your friend, impulse is your enemy.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

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

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

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

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

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

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

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.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

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

The greatest enemy to human potential is your comfort zone

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.
