It's taken me a very long time to conclude about my need for alone time. Before I just used to break through a barrier and wear myself down by ignoring the need to be able to recuperate. I know that this (alone time) is a binding trait felt by most INTJs (if not all).
I always thought it was a selfish desire rather than a need, but when I look back at patterns and mistakes it seems that they all hinge on my limited extroversion being "used up" like it were a precious and rare commodity. It's definitely a "need" not a "desire " for an abundance of reasons for me.
Any one of the same opinion?
