I don't own (or want) an iPod, HDTV, or state-of-the-art computer. When I'm buying clothing (which I hate to do), I look for functionality rather than style. Then I wear it until it becomes worn out. The same for appliances. I've been using the same coffee maker for 14 years, and since it still works I don't have any urge to replace it.
The only exception I make is for river gear. There's a whole lot of "stuff" that I desire in river equipment. But I make due with old gear, and only buy what I can afford. If I won the lottery (which is highly unlikely since I don't play the lottery-otherwise known as a tax on people who don't understand statistics), there's a boat and a ton of accessories I'd love to own.
And I would love to travel more.
What bring this all to mind is the current economic turmoil. While I don't pretend to know what's going to happen in the future, all the signs I see look bad. The falling dollar, crumbling housing market, federal deficit, and generally weak infrastructure just aren't sustainable. Something has to give, and a lot of people are going to get hurt. I know many people who have accumulated debts in the pursuit of more "stuff", and their anxiety is palpable. There's a sense of being on the brink, waiting for the fall.
Which brings me to a simple point. If our economy tanks, I'm in a better position to weather it than a lot of people. I don't have much to lose, and a lot of experience getting by on next to nothing.
