I think this is one of those gray areas where each person has to find the balance that's right for them. I also think some people have an easier time organizing things than others. Don't know if that's genetics or how we were raised or what it is, but I know people who have less to do in their day than me and can't seem to get anything done, and I also know people who have more to do in their day than me and manage to accomplish about ten times more than I do!
I've always been a very organized person, and my mother was obsessive about it - making lists constantly and feeling like she HAD to stick to the plan. I definitely don't take it to that extreme because I don't think it's realistic, and you'll drive yourself crazy trying to do it all, every single day. We're human beings, not machines.
You prioritize, and take care of the things you feel are most important first. Some things can wait, but again I feel that's an individual decision.
For instance, my workouts are a priority for me, but to fit them in I have to sacrifice sleeping an hour or so later every morning. Obviously child care is a priority, and to fit in getting Nik up to school or to the bus stop in the mornings, I have to workout and be ready myself when the time comes to leave. Obviously my job is a priority, hence the getting up early thing again. Spending time with my husband and Nik are priorities, so I'm selfish with weekends. We try to do housekeeping things and shopping in the evenings so we have our weekends free. When I go out with friends, I do it during the week. Nik has music lessons in the evening, and we take turns driving here there so other things can get taken care of by the one not driving her. That's how we free up our weekends. We clean parts of the house at a time, instead of trying to do it all at once. It's overwhelming otherwise. It takes me alone six to eight hours to really clean it well. No way would I give up a weekend day to do that unless you're talking near the holidays and people are coming over. And still in that case, all three of us would be cleaning and it wouldn't take long then. In the nice weather, my husband and I do yard work in the evenings, or Saturday mornings so the rest of the weekend is free.
These are just a few of the things we do, but again everyone's household and lives are different, and you have to find what works for you. Hope this helps!
