I agree extremely on the issue of procrastination not being restful, this is a standard theme in modern productivity writing. Procrastination (like reading blogs / tweets / etc) is a sort of worst of both worlds, it is neither useful nor restful, it passes the time and avoids immediate pain without providing pleasure or renewal.

That's why The Energy Project, Pomodoro, Zen Habits, etc. recommend that you schedule renewal breaks into your day - at a minimum midmorning, lunch, and midafternoon. I think the deliberate practice literature recommends breaks every 90 minutes. Taking a walk outside & exercise are oft-recommended, but really, just being conscious of the goal of renewal and experimenting to find things that will work is all you need. It's helped me be more productive.

Social conversations with co-workers are also good, but it's important that they be relaxed & guilt-free. One of the secrets of renewal is that it works much better if accepted as a need, for some reason guilty renewal doesn't renew. Renewal requires relaxation while guilt prevents it, something like that.

Glad to hear that you're learning (and writing about) basic productivity hacks like this, LW will get its instrumental rationality black belt yet :).
