I've been using what the OP discusses for several years now, and it works. In particular, as a scientist I can report that the brain is particularly creative when it is expected to work on something else; it comes up with very interesting and original research topics that are worth being captured in writing (to be executed later on). The main task can be attacked (better) with Structured Procrastination by making a TO DO list on which we divide it into many small tasks. During procrastination, picking and completing a small task from the list is typically possible, and relatively effortlessly so.
