I have felt very much like this in the past, but no so much any more. .. my thinking is:
Some things are just part of the responsibility of being a grown up. Home maintenance, driver for children, doing taxes, etc. These are your baseline priorities that you don't get to choose.
Some of these sound like they occupy a rotating priority slot. House and car purchases do take a big commitment and require prioritization (especially if you build) but they are temporarily a priority. It is usually your choice to make these a priority, and they are rare.
Keeping a smaller priority list means saying 'no' to more things too, like being 'tech support geek for wifi and computer issues' or vehicle maintenance. These priorities are fully under your control.
