This is sort of a personal preference, but I tend to find that I work best with an imminent deadline. Before this, I would sometimes not doing anything all day and then rush to get things done before the end of the day. Splitting it into parts gives me an artificial deadline that helps me focus my energy a little better. Also, taking the breaks in between each set of tasks helps with a sense of accomplishment but also just gets me moving so I'm not in front of a screen for 8 hours a day straight.
