I'm usually coding for probably even shorter time periods because I'm taking some breaks, but when I'm consumed by something that's all I'm thinking about even when doing some other tasks (eating, shower, groceries etc.) I don't know how other people work but I just wanted to point out that at least for me often the reason for lack of focus seems to be not being 100% convinced that I want to do given thing. Because in reality there's usually plenty of reasons for doubt. So it takes some kind of "I don't care how rational that is, I just really want to do it".
