I am wondering if it’s OK to do things at the same time every day. This means that if something overlaps with a thing on my schedule the least important thing will be completely skipped for that day. Normally this would be things like meals or errands/chores. Don’t worry I will not be overlapping too many things in my schedule so that things just keep getting missed or put up off.
Well, yes...to a degree. But it's always good to allow for flexibility or spontaneity. You can always eat a bit later if shopping takes you longer, or eat earlier because you're meeting a friend. It's what most people find works best.
