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

Your limitation - its only your imagination.

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

If you want to succeed, double your failure rate.

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

It always seems impossible until it's done.

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

The road to success is like a staircase. If you want to succeed, double your failure rate

The temptation to quit will be the greatest when you are about to succeed

Failure to prepare = preparing to fail

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.

In order to become better than anybody else you must first become better than yourself.

There are no bad mistakes in maths, only discoveries.

The easiest person to deceive is yourself.

Hard work - a two way street where you get exactly what you put in.
