Oh come on people... This one was rougher than the rest. Americans watch 4 hours of TV per day? Source? (Ok, there's Google, but that's not the good-old footnoted style.) Next, a bunch of fairly obvious things (TV is a time sink, so are other forms of distractions, and distractions prevent you from doing work!), then a submarine (plug for a personal investment).
The "solution" of separating out a work machine isn't particularly insightful either. I've done this before and I bet many others have also, and its efficacy depends highly on the person. (interestingly, I would guess that those who are very good at focusing wouldn't have to employ as many tactics to prevent their distraction).
Indeed, this wasn't the peer-reviewed kind of essay that normally gets linked here, but probably an inspirational thought-stream writing. Pardon my lack of tact, but given the ever-warm feedback to all pg essays alike, this one was, frankly, comparatively bland.
