The master has failed more times than the beginner has even tried

Time is your friend, impulse is your enemy.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

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.

If you fail, next time fail better.

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

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

You can have results or excuses, not both

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

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Nobody said it’d be easy, they just promised it would be worth it.

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

Try and do one thing each day that you would really rather not do.

The greatest enemy to human potential is your comfort zone
