“The first requisite for success is the ability to apply your physical and mental energies to one problem incessantly without growing weary.”

If we did the things we are capable of, we would astound ourselves.

Opportunity is missed by most because it is dressed in overalls and looks like work.

Genius is one percent inspiration and ninety-nine percent perspiration.

Many of life's failures are people who did not realize how close they were to success when they gave up.

If you don't know where you are going, you will probably end up somewhere else.

Never mistake activity for achievement.

Failure is an option here. If things are not failing, you are not innovating enough.
