In my experience, the sort of effort you put in and the work that you do in planning in this multitasking, unfocused mode is not nearly as immediately urgent or productive as it feels at the time. If you are able to cultivate a degree of concentration and mindfulness, then when the time is appropriate you are able to consider whatever matter actually demands your consideration, and respond with sound judgment and openness.
EDIT: Perhaps more to the point, many of the useful decisions or notions that might have arisen from thinking about the future or the past while washing dishes tend in my experience to arise more or less of their own accord, in their own time. Much of the mind tends to think itself once you let it.
