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

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.

A book a day keeps the stupidity away.

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

Failure to prepare = preparing to fail

99% of genius comes from hard work, the remaining 1% comes from innate talent

It always seems impossible until it's done.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.

It doesn’t matter where you start, it matters how you end

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.

Failure is NOT your destiny. Failure is the key to success.

Time is your friend, impulse is your enemy.
