Hyman G. Rickover said this quote

Nothing so sharpens the thought process as writing down one's arguments. Weaknesses overlooked in oral discussion become painfully obvious on the written page.

~ Hyman G. Rickover

I believe it is the duty of each of us to act as if the fate of the world depended on him. Admittedly, one man by himself cannot do the job. However, one man can make a difference. We must live for the future of the human race, and not for our own comfort or success.

~ Hyman G. Rickover

When doing a job — any job — one must feel that he owns it, and act as though he will remain in that job forever.

~ Hyman G. Rickover

What it takes to do a job will not be learned from management courses. It is principally a matter of experience, the proper attitude, and common sense — none of which can be taught in a classroom... Human experience shows that people, not organizations or management systems, get things done.
