By “performer” do you mean musician? Playing bars or coffee shops here and there? I’ve done that for a free drink or two here and there. I think that would be one of my retirement activities if I had loads of free time, but it takes a lot of energy to set it all up and be “on” regularly while also working full time.
My wife offered to cut my hair. I told her no. She’s a very clumsy person lol. I also have a Wahl clipper, but it’s for trimming my beard.
