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

The easiest person to deceive is yourself.

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

The wise person knows that no answer is also an answer

Your limitation - its only your imagination.

If you can understand just one thing thoroughly, then you will understand everything.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

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.

Just stick with it, what seems hard now will one day be your warm up.

We learn more from failure than we do from success.

I think, therefore I am.

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

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

If you fail, next time fail better.
