Thanks, that's a lot to think about. We currently use an oled computer monitor as a TV (hooked up to a pi) and it's beautiful but there are limits on screen size and it's crazy expensive (you're paying for stupid fast refresh rates and the Gamer(TM) markup)
our house is very bright during the day, lots of glass in sunny Australia, so it's probably not a great candidate for a projector generally but it does have me thinking about one in the bedroom for late night movies. Probably a lot cheaper and neater than another absurd monitor.
Find a sense engaging ritual and do it regularly.
For me it was having elaborate spice teas or herbal teas. I'd mix up batches and keep it in the office, when I needed some sanity taking the time to just focus on a damn good cup of tea helped me relax some.
A treat you enjoy, a stretching routine whatever you can do that is highly engaging would be a good choice. Force work out of your head even for 5 minutes. We aren't meant to work like a steam engine.
