Edgar A. Guest’s “It Couldn’t Be Done” (“There are thousands to tell you it cannot be done, / There are thousands to prophesy failure, / There are thousands to point out to you one by one, / The dangers that wait to assail you. / But just buckle in with a bit of a grin, / Just take off your coat and go to it; / Just start in to sing as you tackle the thing / That ‘cannot be done,’ and you’ll do it”),
