My last teaching gig (local community college) paid extra for teaching extra classes, so I drastically scaled back my ms type side gigs in favor of the much more profitable teaching of extra classes.
Since retiring from teaching in November 2020 I have jumped back into the side gigs that we all do, but with conditions.  My main condition is that my vehicle will not move unless I make $1/mile.  In 2022 I made $2/mile on average.
In 2022 I quit a movie theater cardboard standee/display assembly job (pretty good money, but too physically demanding for this old man!) and was removed from the doctor's office brochure display replenishment jobs by Customer Impact after I wanted to give up one unprofitable route, but they removed me from all 4 routes that I did for them (bummer, oh well).
It seems like everyone here is doing some good analysis of their side business activities and are setting their own set of policies and guidelines for the work that they will do and won't do.  Seems like entirely sound strategies to me.  Good luck to everyone out there in 2023.
