Interesting topic, Ludi, and one that I'm glad you started
For me, negativity is knowing a future that most people do not know, or flat-out deny even if they really do "know." For me, being negative is being born 100 years too soon, and living in a world that I know to be totally unsustainable...a world of mixed-up value systems, ecological destruction and war that seems to know no end.
When I was a kid, I saw all the new stuff being built, and wondered how long this could go on. Until the whole country was paved over? I wondered how long the oil would last, I wondered how people would survive when there were too many people and too few jobs. When I was a kid, I looked ahead into the future and saw the US fighting endless wars over the black stuff we just had to have, for how could we continue our way of life without it??
And now, at the age of 40, I see all of these things coming true, and yes, it does make me negative, angry, depressed and all other kinds of emotions in between (look at some my earlier posts on here, and you can see what I mean...LOL). BUT, I do see the positive side of things, and I know there is reason to hope. Somewhere, somehow, somewhen, there will always be reason to hope that we will someday "get things right." And like I told a friend a long time ago, I will stop being depressed when the rest of the world goes into depression, and I still think this to be true, as I will finally be living in my own element.
Now, in this time, work ("a job") is the worst thing in the world (kudos to your godson, Grifter...he must have a bit of me in him...LOL), in the coming depression, work will probably be the best thing in the world, as I'll be doing things that I find to be extremely rewarding. So I spend my endless free time learning as much as I can about everything and getting ready for what I know is soon to come...and learning how to decouple myself from the materialistic world around me, and I do have to say that it's really starting to pay off, especially as more and more people realize the futility of being enslaved to "things" and "status".
Ludi, I just want to give a big serving of praise to you for doing what you feel is right, and being positive for the rest of us. Yeah, I know this must feel like hand-to-hand combat warfare sometimes, but like someone said over on the HousingBubbleBlog once, you gotta count your victories when you can, even if it's one person at a time. And yes, your cause is definitely one of inspiration to many.

Whatever you may do, whatever may come of all this, please don't ever give up fighting the good fight (sheds a tear or two...)
