Hehe I seen the bad side hit more than good, but it happened to people who tossed away dignity. Live and learn, if they don't then I learn from them. Study their mistakes and don't repeat it, reason history is such a popular lesson in schools.
I love History! And I certainly am similar in the respect that I do take on board people's mistakes so as not to make them myself. Well, it's probably not as grand as that sounds. I try to live my life in a certain way; "get by, don't fuck anyone over, have fun", but that cuts out a lot of potential mistakes in how I treat people, so maybe I'm lucky.
But then again, the flipside is that perhaps those who don't really care about how they might treat others "live" more, if you see what I'm saying. I've seen this amongst people that I know for sure.
