Life is full of opportunities. With every opportunity that is missed, another one is born.

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

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

Mistakes have the power to turn you into something better than you were before.

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

If you fail, next time fail better.

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

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

Run in the morning before your body figures out what you're doing

There are no shortcuts to any place worth going.

The journey of a thousand miles begins with one step. 

It always seems impossible until it's done.

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.
