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

The temptation to quit will be the greatest when you are about to succeed

I can is 100 times more important than IQ.

If you fail, next time fail better.

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.

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

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.

Skills are built not born.

Knowledge is of no value unless you put it into practice.

We learn more from failure than we do from success.

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

Your limitation - its only your imagination.

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

You're not in competition with anyone but yourself. Outdo your past, not other people.
