Is "happiness" a biological/hereditary trait?
If so, it's pursuit seems rather irrelevant.
I'm not talking about the ideal concept of happiness, more like the little things that make some people happy and have no effect on others.
Of course, nothing that behavioral is 100% bio, there is also a cognition component to it. I'd say 50%-50%.
I was with 3 friends out tonight and one of them said that I always seem rather melancholic, pointing out that all of us have a default mode and that's mine, but I don't necessarily see myself as melancholic all the time. The idea is that one of my friends is my opposite, he's always happy with basically very little.
And most people I know have this default mood. I see my mood as neutral, not necessary unhappy.
So if unhappiness is regarded as being somewhat biological, can we say happiness is the same?
Can we assume that achievement is not necessary in order to reach some kind of self satisfaction? Because most overachieving people don't seem that happy, it's the ordinary people who seem to be happy, living a simple life, without too much fancyness.
( I specifically chose achievement, because that's the most common happiness myth)
Of course, my view on this issue seems terribly one sided, ignoring the rest of things, but I'm willing to give biology a 50% slice, if not more.
