I do agree - my one daily life hack is to do everything I promised myself I would do that day, plans-wise. And unsurprisingly, this has caused me to simplify my plans. Now I don't plan on going to the dry cleaners, the gym, the grocery store all in one day. Now it's just one, and I accomplish that and so I don't have to get into a negative self-loop.

I do think the question of shopping, cooking, etc *is* harder than we might think at first glance, and that there was a reason that you could get a masters degree in home ec at one point.
