Sort of, but now I use my own 4x4 method. 4 blocks, 4 hours each.

5-9: Routine sprint that consists of breakfast, getting son ready for school, taking him to school, exercising, meditating, personal writing, and bath time.

9-1: Planning sprint that consists of meetings, researching, outlining, scheduling, and eating lunch with my wife :).

1-5: Work sprint that consists writing, editing, building, and project managing.

5-9: Quality time sprint that consists of picking my son up from school, taking him to soccer, playing & chatting with him/wife, cooking dinner, bathing him, reading him a book, laying him down to sleep, and then cleaning his aftermath lol.

9-11pm is free time, usually my wife and I do something together... watch tv, exercise together, talk, paint. Whatever sounds fun.
