Phlegmatic

Low extraversion and low reactivity: quiet restores you, and events rarely knock you off balance. The standard description makes this corner sound dull, which is unfair. Steadiness isn't an absence of feeling — it's a different tempo of it: things reach you no less, just slower and without the spike, and you decide after the first wave has passed for everyone else. That's why people like you are worth the most in a crisis: while everyone reacts, you simply keep doing, and your voice stays level precisely when a level voice is worth more than advice. You'd rather work at your own pace and to the end — the long stretches that put a sanguine to sleep don't bother you. The vulnerability is symmetrical to the strength. Level reads from the outside as indifference, and people who need to see a response sometimes get no signal from you at all, while you're certain you sent one. And what doesn't knock you over doesn't move you either: a situation that has needed changing for years can be endured for years, simply because enduring is something you're better at than most.
