Hobbies really help with this (Public Board)
Humans are basically evil I have determined. The people that live around us certainly are on the low end of the effort/goodwill/morality/self sacrifice/ability to think scales just like the people i went to high school with, most people I worked with, etc. Leaders are no different.
So you'd say that humans in general have always been like that? Some say that people are worse these days, after the invention of the smart phone and social media.
