A true executive can sign a poor letter without changing it

Gretchen Rubin pointed out this story in the Jan. 7 micro-episode of A Little Happier:

When Nixon was president, an advisor drafted a letter which he thought didn’t strike the right tone, and he sent it anyway, and repeated to an aide something that Eisenhower had once told him: “A true executive can sign a poor letter without changing it.”

The quote came from President Nixon: Alone in the White House, by Richard Reeves.
