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

My success is due more to my ability to work continuously on one thing without stopping than to any other single quality.

The secret of success is focus of purpose.

The reason I've been able to be so financially successful is my focus has never, ever for one minute been money.

If there is any one secret of success, it lies in the ability to get the other person's point of view and see things from that person's angle as well as from your own.

Focus on your customers and lead your people as though their lives depend on your success.
