I don't see why happiness is in the equation at all. happiness to me comes from within the self and is not swayed by external circumstances easily. Because you can not control the world it is best not to rely on things or situations for gratification. To me the world is separate from emotion which only exists with in myself. By putting that aside it gives a clearer view of how to handle situations for maximum efficiency. This includes putting aside the will to make people happy or to be self sacrificing which to me is martyr ish. It serves no purpose to anyone if everything is functioning to its capability.
Hmm... I'm not too sure what you are talking about here... Your profile says you are ENTP, and you still claim that you have separated your happiness from outside world. Sounds strange. I'm introvert and for me it should be a lot more easier to find happiness inside myself, but for me it doesn't work that way. Besides, if you really feel that the F-people creep you, isnt it same as saying that the feelers are disturbing your happiness? This means that your happiness is also dependent of the outside.
But, anyway... I don't think it is anyhow possible to make your happiness independent from outside world, and this is very important point if you want to understand feelers. The reaction that you get from us differs, but the reasons are pretty much the same. If I am in a conflict situation, it gives me this feeling of helplessness and starts actually feeling as a pressure on my chest. Its something I cant stand. I want to get out of it, and if theres a way to make the conflict stop, I'll try to. But, to someone else it could be something more irrational, which might seem to you like they've gone nuts. This goes for all the situations concerning other people. I want people to be happy with each other, and I usually don't do anything that would lead to a situation that is painful to me, in other words, I very rarely act in the way you described feelers in your earlier posts.
I'm not sure if anything I just said has much to do with the topic, I'm not so sober anymore. Anyway, I guess I want to say that with people you should never rule out happiness as motivation. Everyone wants to be happy.
