This discussion has been had before with perhaps a slightly different twist. My question then as now, is: What does "happiness" mean in the current context? I am happy when I practice my guitar playing and it goes well - it makes me feel satisfied ( and conversely). I am happy when I see that my children are good people and they seem satisfied with their lives. I am happy when I see someone lending a helping hand to someone in need. I could go on - but my point is that, to me, "happiness" is not a state that simply exists without a context, a situation giving rise to certain reactions. Being happy all the time would, it seems to me, become quite boring.
