I’d like to do 4-7 hours of work a day. I’d probably like to work 2 days, then have a day off, 2 days, a day off. Or work every day, but only do 3-4 max hours a day with it being fully flexible when. I’d like to take opera singing lessons every other day for half an hour or max an hour. I’d choose to work during hours when people are usually off and enjoy more empty cityscape when people are usually at work. If my health allowed, I’d love to regularly donate blood again. I also wouldn’t mind regularly volunterring for a cat charity or something like this. Maybe I’d volunteer in a communal city garden, but leave just before most people come.
16 hours a week would be great for work, or less if there aren’t any deadlines to hit. The rest would be learning to program, playing games, painting, reading, doing outdoors activities like pickleball/volleyball/tennis or just going for hikes/walks and taking the dog to the parks.
