Success is not final, failure is not fatal.  It is the courage to continue that counts.

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

Fall down seven times, stand up eight.

Your attitude is everything. Pick a good one.

No one starts out on top. You have to work your way up.

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

Go as far as you can see, when you get there, you’ll be able to see further

Don’t be afraid to work hard and find out how good you can really be.

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

Instead of finding reasons why you can't, find reasons why you can.

We learn more from failure than we do from success.

The master has failed more times than the beginner has even tried

The wise person knows that no answer is also an answer

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

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