I often have problems communicating with other human beings because I use some words with a different meaning/weight. For example, if I say that I'm egoist, people will immediatly picture in their mind some hideous being who profits and takes advantage of others for his own well being and doesn't feel guilty about it. But that's not what I meant.
I mind my own business without interfering with other people (or trying to not interfere), trying to solve my problems and get by alone. No one helps me and neither I want their help; I don't want to go out of my way to help someone else either. If someone is troubled by something, it's not my problem and I won't care or go out of my way to solve it, even though I could potentially solve it. I care only for myself but, in doing so, I try not to abuse or take advantage of others. Actually, I avoid unnecessary interaction with anyone. I already got my spare of troubles, why should I care about others?
How would this be called? I tried researching words like selfishness, egoism, egotism etc, but it always comes up with the "taking advantage of others" or "manipulating others in doing what you want" etc.
Now, I'm of the idea that everyone is selfish, deep inside (everything we do, it's because we want to do it, not because we care for someone else http://en.wikipedia.org/wiki/Psychological_egoism ) but, once again, "selfish" also has additional negatives attached to it and so it isn't exactly the correct word.
Do you know what comes closest to what I described above? Only caring for oneself without necessarily directly harming someone else, how's that called?
