It's also very unambitious.
Life's also about working to get what you want, then enjoying what you wanted so much, then realizing that you wanted something more, and then working harder to get that as well.
If you are always happy with what you have, then, by definition, you don't want anything else. As much as I would love to be happy, the way I see it, if you are always happy, you have already lost. Unless, of course, you have already made your billions.
I'm happy now. I imagine I'd be more happy if I had more stuff/cash, for some definition of happy. Therefore it's good now and it only gets better.
The problem starts when you decide that you don't have enough, and this makes you unhappy. Then you pursue the stuff thinking it'll make you happy. Starting from that viewpoint, I don't think it ever will.
