Thanks for sharing! This is a very good and pretty exhaustive list! I also like to plan my day ahead and group certain activities together. I often enter flow state while programming and last thing I want is waking up for another meeting.
Thanks for sharing! #2 is a big discovery for me, will def start using.
Couple more recommendations from my side:
Send pre-read documents
Don’t mix content and process in a meeting (ie no deep dive in the content when discussing planning)
Use Vowel for videoconference where heavy notes need to be taken, it has an accurate transcript feature, no need to take notes like crazy.
Eat less often (not less!). Will not only save you time, but also will make you love longer and younger (cf David Sinclair podcasts on this) - oh it will also make you save more and destroy less the planet.
Take calls while walking.
Use Fiverr or other freelance platform for a lot of random tasks eg looking for the cheapest flights to go from A to B to C.
