I came across two pieces of advice which I pass on for your edification and amusement.
The first is a World War II memo from Winston Churchill on Brevity. A copy is below and attached.
"Biden referred to a well-worn story about how, as a freshman senator, he saw Jesse Helms, the archconservative North Carolina Republican, ripping into a piece of disabilities legislation. Biden was furious about it and began attacking Helms to Mike Mansfield, the Democratic Senate majority leader. Puffing on his pipe, Mansfield asked Biden if he knew that Helms and his wife had adopted a disabled 9-year-old boy no one else would take. “Question a man’s judgment, not his motives,” Mansfield instructed.
Biden, who was invited by Helms decades later to give his eulogy, is convinced that absorbing Mansfield’s advice is what allowed him to work with Senate Republicans during the Obama years, to negotiate the approval of the New Start nuclear-arms-reduction treaty, the end of “don’t ask, don’t tell” and the expansion of the earned-income tax credit, among other accomplishments. His approach to Trump, he said, wouldn’t be fundamentally different. “It falls in that category,” Biden told me. “It’s one thing to say: ‘I think the proposal on the following is a serious mistake. I think it’s gonna do the following damage.’ It’s another thing to say, ‘The guy’s a f___ing idiot, and he is an egomaniac who’s a whatever.’ ”
