QUOTE : Assume, for example, that your Twitter habit effectively consumes ten hours per week. Thoreau would note that this cost is almost certainly way too high for the limited benefits it returns. If you value new connections and exposure to interesting ideas, he might argue, why not adopt a habit of attending an interesting talk or event every month, and forcing yourself to chat with at least three people while there? This would produce similar types of value but consume only a few hours of your life per month, leaving you with an extra thirty-seven hours to dedicate to other meaningful pursuits.
