I went through a particularly bad phase and was unable to sleep for about a week. I wasn't violent but to say i was a rational human being after 3 days would be a lie. I don't have a lot of memory but i remember thinking my leg had been cut off and what would happen if i tried to wiggle my toes, only to realize that i still had my toes.

On the flip side: executive leadership positions tend to end up with quite a few psychopaths.

As long as they don't step over the line of what their privilege and power lets them get away with, they keep heading upward.
