For many years I was a self-appointed inspector of snowstorms and rainstorms and did my duty faithfully, though I never received payment for it.

Do something every day that you don't want to do. This is the golden rule for acquiring the habit of doing your duty without pain.

There is no duty we so much underrated as the duty of being happy.

When a stupid man is doing something he is ashamed of, he always declares that it is his duty.

A sense of duty is useful in work but offensive in personal relations. People wish to be liked, not to be endured with patient resignation.

Duty. That which sternly impels us in the direction of profit, along the line of desire.

The first duty of life is to be as artificial as possible. What the second duty is no one as yet discovered.

How can we know ourselves? Never by reflection, but only through action. Begin at once to do your duty and immediately you will know what is inside you.

The sense of obligation to continue is present in all of us. A duty to strive is the duty of us all. I felt a call to that duty.

He who is false to present duty breaks a thread in the loom, and will find the flaw when he may have forgotten its cause.
