This is an old thread
not sure if people noticed?
It's a good thread, though, some really good answers out there already... Coyote, Pingu, Puma, vj, Mr Vabanque, McGee...
Maybe OP was just burnt out at the time? It can happen, if you treat others well and then it may not show results like you'd like to?
Personally I think 80% people are good
2% or 0.99% maybe aren't (and even they can mend their ways), the rest is inbetween...
Louise Hay's book says that if you imagine most people are good life can be much easier and they will treat you much nicer too... and I think it's true...
Another book said, if people behave 'bad', don't change hardware, change software... (way of thinking/re/acting and/or communication to them) An older boss told his son to not fire a worker who has done something bad: 'he can learn from his mistakes, it's important to educate... If you just fire anyone when they make a little mistake, you'll never have good workers...'
So yeah, it's important to distinguish 'people' from 'actions'...
Sometimes people do project things, sometimes make assumptions based on previous (limited) experiences... It is good to have some hesitations and reservations and be careful and assertive if necessary... Even good people can sometimes do 'not so great' things, usually they don't mean to do harm, they just don't know any better or have had a bad day or don't know the relevant factors or that it might even bother you, or maybe they just wanted to do some friendly teasing... They may just have different priorities or lack of knowledge.
