Apparently created by a supply company as suggestions to go on their products I think now we might be able to riffle it for clip art and t-shirt slogans. "Out of the quiet harbor into the billowy sea" or "Backbone, not wishbone" or what has to be an oddly uninspirational Patriotic Motto "We struggle to win". There's even some in French ("Nul bein sans peine" - "No pains, no gains") and Latin ("Dignus Vindice nodus" - "A knot worthy to be untied").
