Most calendars you can break down to w.e. interval you want, I share a calendar with my family and we put our stuff up. Then for each bucket, I break it down individually as the day comes up. Takes like 10 min at night to put it all in, so maybe an hour a week of planning. That may seem like a lot, but worth the effort IMO.

As an example, every day my basic schedule: 6-8am with family, 8am-12pm [farm] work, 12pm-4pm [collaborative] work, 4-7pm chores & family, 7-9pm [emails / focus work] work, 9-10pm family, 10-12pm [focus] work.

Then the day before, I will break out individual events. There are times, for instance, I have to take a kid to the doctor so I'll block that out, put in all my meetings and adjust the 4-7pm family time to say 5-7pm (take an hr from work & family time).

It's all about being disciplined and trying to ensure you are organized and maximize time for me. Gotta keep focused
