Your second point has always been really helpful for me. Since. I spend all day basically living in my own head and moving bits around to create intangible products. I find that it helps to do some activity with more tangible results, to avoid burnout.

My current activity is cooking. I make the time most nights to make a real dinner from scratch. I've gotten in to bread baking too. The part that I think is most beneficial is both that it produces something that you can actually touch (and taste) and I can finish preparing a meal in an hour or two, so I don't have to wait for months to see the outcome of he thing I am creating. Plus it doesn't hurt to have a solid healthy meal everyday.
