If you felt any pangs of indignation or self-righteousness while reading about other people’s behavior in this book, try hard to un-feel them. That boss who calls “unnecessary” meetings might well be you (though of course you won’t see them as unnecessary). That friend offering smug advice? That’s you too. This kind of self-knowledge is the small gift that Robert Burns pined for in his poem “To a Louse”: to see ourselves as others see us.
