I read the first half of the article just screaming "He's doing it wrong!" However I later realized that was the entire point of the article.
For my part, I've decided there's nothing else I'd _rather_ be doing. It's the only thing in life I can reliably count on to provide a satisfying, enriching experience. The material/hedonistic experiences are still important to me, and most of my time is still spent on them, but they're all pretty transient in comparison.
