I tend to operate under the assumption that you don't find it, it finds you. If I do the right things and treat people well and love my family then I'll be happy with myself and general happiness will insue.

But to put a finer point on it:

My family, especially my kids, give me joy.
My work provides satisfaction and worth (spiritual and monetary).
My home provides comfort and well-being (and an endless source of stuff to fix, which I like to do so that brings its own positive feelings)
My friends, colleagues, neighbors, school chums, clients, store clerks, car mechanics, first responders, members of the military, et al, provide companionship, support, conversation, good memories, and service. In other words they provide the things that make life both fun and possible.
My countrymen and women proffer solidarity in times of crisis be it national or local.
My elected leaders provoke, entertain, frustrate and occasionally pleasantly surprise me.
The folks on this forum educate and encourage me to prepare better, think smarter and open my eyes and mind to new ideas.
My beloved Fightin' Irish, sigh....

All the other crappy stuff in my life, like bad drivers, rude people, closed minded, prejudiced lunks, Linux, etc., etc., is just that crap and I try my best to deal with it, ignore it or flush it.

I am I giddy everyday? Hell no. But when I kiss my wife or hug my mom or take that collect call from a DD Ihaven't seen in months, am I happy? Damn straight.
