I'm not sure about the specifics of the method as described in the book, but time blocking is a pretty standard technique (if you google "time blocking" you'll get dozens of tutorials on it). I've been blocking out time on my calendar for a year and a half now. It definitely adds value, as I know what I should be working on in order. Doing it on a digital calendar also means that I can move stuff around or add tasks quickly as plans (invariably) change. When trying it as my only method of planning, I found that I was losing the bigger picture and losing track of key tasks. For instance, if I put some task to do for Friday but don't do it and forget to reschedule, it's just lost in my calendar. However, it works quite well with an external todo list, as a way to make it more concrete. It can add or remove stress depending on how you use it. At first I blocked out too many things per day and would get stressed from not finishing them. Now, I block out maybe 2-3 main tasks which I can usually finish and feel good about spending time for myself in the evening.
