As a 60% Introvert (according to the MBTI – always somewhere around there) – I can completely relate! ( My definition of introvert: After spending time with people, an introvert needs to recharge their batteries by being alone for a bit. An extrovert, just gets more and more energy when around people).
The percentage thing helps because yeah, sometimes I get energy when I’m around people. But it depends on the people and the situation. Usually I gotta vanish for a few minutes someplace now and again when I’m around people for extended periods of time.
