I had to laugh at Bulbasaurs "mental energy", since I expend a fair amount of mental energy on not cleaning, divided between calculating whether and when things need cleaning, and how to do it efficiently.
For example, I cut up all the ingredients for a dish in a certain order, so I don't contaminate the single knife and chopping board I am using. Contamination is not just from meat, but from onions as well: awful to chop "harmless" vegetables with the wreath of onion fumes rising from the board!
I will mop up water or non-red juice spills with a bath towel or tea-towel which is awaiting a wash, thereby saving kitchen roll. The towel will go into a hot wash with Napisan anyway, so...
It is important to ration out mental energy devoted to cleaning, and do it rationally. Just now, I'm whipping a former rental place back into shape to hopefully get all or most of our deposit back, so I haven't yet done any mopping or sweeping of the house we've moved into, and I'm also feeling rather "Christmas Schmismas"!
I'm also being very short with my mother, who is being really helpful but also really over-energetic at times when I just need to shut up and recharge, and not answer questions about where the next ten things go.
Just because there is a lull of half an hour before the school run, that does not mean it has to be filled with sorting or housework, however much "needs to be done". At such moments, I can see a pile of laundry with complete indifference, and turn back to my book, newspaper or MN, since those are refreshing!
