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

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

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

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

The journey of a thousand miles begins with one step. 

Everything you want is on the other side of fear

Success can never happen without the journey (struggle).

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

Success is the sum of small repeated efforts, day in and day out.

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

Skills are built not born.

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

99% of failures come from people who have the habit of making excuses.

It always seems impossible until it's done.

Pure mathematics is in its way, the poetry of logical ideas.
