“What happens when that recently triggered mood lingers? You’ve been in a bit of a funk since that day, and now you look around the room during a staff meeting and all you think of is that this person’s tie is hideous, and the nasally tone of your boss is worse than nails on a chalkboard.

At this point, you’re not just in a mood. You’re reflecting a temperament, a tendency toward the habitual expression of an emotion through certain
behaviors. A temperament is an emotional reaction with a refractory period that lasts from weeks to months.

Eventually, if you keep the refractory period of an emotion going for months and years, that tendency turns into a personality trait. At that point others will describe you as “bitter” or “resentful” or “angry” or “judgmental.”

Our personality traits, then, are frequently based in our past emotions. Most of the time, personality (how we think, act, and feel) is anchored in the past. So to change our personalities, we have to change the emotions that we memorize. We have to move out of the past.”
