Not wanting anything does not necessarily imply a Zen-like state of being one with the universe staring at the sky in eternal bliss. It may mean feeling empty, directionless, amotivated, detached from everything, a modern Sisyphus rolling boulders in a meaningless, absurd universe. So be careful what you wish for.

Unless you get that feeling because you, say, suffer from depression (as I do), where that might progress to "I don't even want to be alive."

But even before that, the feeling isn't one of having everything you need already. It's one of almost crippling apathy.

Hehe. It's very true though. I think one of the primary reasons I feel happier now than when I was younger, is that I want much less. Or maybe my ambitions have become more realistic. Either way, I like it.
