If you're going to seek anything, seek what gives you enjoyment -- that's if you know at least the components, like art, music, writing (not necessarily one's own --
), films, good TV (I think my favorite is now Smithsonian Channel but I do have many guilty pleasures!), and perhaps end up with relationships that are centered around mutual enjoyment of those things. It's definitely not getting preoccupied with politics and the daily onslaught of bad news on CNN. Or, like I stated before, happiness is just not being unhappy. Depression is unhappiness and it may not be one's fault, like environments or bad relationships one has dropped themselves into not just from naivety but from wanting constant change, or just a physiological bad mixture of chemicals in the body and brain (we know that can be self-induced!). Often there's a decision of a change in environment which is not a bad idea in itself, it's that changes sometimes are the causes of the unhappiness.
That's one reason I enjoy history -- it's remote, one can learn from it, and it doesn't make me unhappy. Mentioning Smithsonian, their recent Apocalypse series on WWII utilizing a lot of the same color footage that was on the simultaneous History Channel WWII in HD, won that "Battle-of-the-Documentary-Networks" by a slim margin.
It also make me curiously happy after reviewing a war that was at least inevitable at the time and had some purpose, good or bad (whatever one thinks about that) to again realize that Bush and Co. was a gigantic bag of **** -- starting two wars they had deluded themselves into thinking they could finish, or someone else could finish them and they could be at home and just observe, unfortunately moving their lips from time-to-time.
