Is there such a thing as being too frugal?

I consider myself frugal, and yes, a tightwad. I admit that I'm very cheap.

My husband shakes his head often at my cheapness and the fact that I will pick up things from the side of the road and out of dumpsters. I have to do that when he's not with me though, because he won't stop the Suburban when I spy a treasure.

I recently read this piece, Extreme Frugality: Taking Cheapness to the Extreme and I had to shake my head.

I guess I'm not into that kind of extreme frugality. Oh I appreciate some creative thinking when it comes to saving money, but some ideas. . .nope.

So what do you think?
