Theodore Roosevelt actually said...

I ask of you the straightforward, earnest performance of duty in all the little things that come up day by day in business, in domestic life...

I demand it of you as a right, and hold you recreant to your duty if you fail to give it.

it is even a greater thing to be what all of us are—Americans.

That is the spirit of devotion to the flag and the country, and to one's fellows which the United States navy develops.
