“Here are some key attributes of the voice in my head. I suspect they will sound familiar. • It’s often fixated on the past and future, at the expense of whatever is happening right now. The voice loves to plan, plot, and scheme. It’s always making lists or rehearsing arguments or drafting tweets. One moment it has you fantasizing about some halcyon past or Elysian future. Another moment you’re ruing old mistakes or catastrophizing about some not-yet-arrived events. As Mark Twain is reputed to have said, “Some of the worst things in my life never even happened.” • The voice is insatiable. The default mental condition for too many human beings is dissatisfaction. Under the sway of the ego, nothing is good enough. We’re always on the hunt for the next dopamine hit. We hurl ourselves headlong from one cookie, one promotion, one party to the next, and yet a great many of us are never fully sated. How many meals, movies, and vacations have you enjoyed? And are you done yet? Of course not. • The voice is unrelievedly self-involved. We are all the stars of our own movies, whether we cast ourselves as hero, victim, black hat, or all three. True, we can get temporarily sucked into other people’s stories, but often as a means of comparing ourselves to them. Everything ultimately gets subordinated to the one plotline that matters: the Story of Me.”
