Your attitude is everything. Pick a good one.

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

Do what you have always done and you will always be what you have always been

He who has begun his task is half-way done. Have the courage to begin!

Practice like you’ve never won. Perform like you’ve never lost.

It is never too late to become what you might have been

The greatest glory in loving lies not in never falling, but in rising every time we fall.

You can have results or excuses, not both

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.

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

The greatest mistake we make is living in constant fear that we will make one.

Patience is when you’re supposed to get mad, but you choose to understand

Skills are built not born.

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

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