Thank you for sharing this. Keep up the good work and healing, OP! It's incredible that you've continued to be polite and to do as much as you can through your health struggle. Setting and enforcing boundaries can be difficult for some, especially when you're feeling hazy and not operating at 100%. I like that you pointed out being polite can be expensive sometimes.

This is excellent advice for anyone with knowledge based work though. Distractions, messages, pop-ups, asks, meetings, etc. are the leading reason I don't get as much done as I could. Some of your items could definitely help here.
