We learn more from failure than we do from success.

There are no shortcuts to any place worth going.

Hard work beats talent when talent doesn't work hard.

Procrastination makes easy things hard and hard things harder.

The journey of a thousand miles begins with one step.

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

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

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

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.

Success can never happen without the journey (struggle).

Your limitation - its only your imagination.

Failure is NOT your destiny. Failure is the key to success.

You cannot escape the responsibility of tomorrow by evading it today

We all have two lives. The second begins when we realise we only have one. 

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