I enjoyed this. I was raised Catholic and they had a similar kind of thing, but on a day-by-day basis. Before you went to bed you would think back over your day, reflecting on your behavior -- what you did right and what you did wrong. More of a moral inventory than a gauge of personal efficiency.

I'm an older person nearing retirement, so my situation is different. But I can't help thinking that focussing on efficiency to this extent is detrimental. Jacques Ellul would say that "la technique" has taken over your life.

I found your post on ultra-bright interior lighting to be very interesting. I think I would go with two mega-bright lamps without fans than one giga-bright fan that needs one.
