Great article. I have found several of these true over 20+ years developing and managing. The "turn off email" or even "put on do not disturb on all devices" is a big one for me I put into action a year or so ago. Definitely helps keep the flow and concentration going.

Almost like a surgeon, you get through all the layers to find what you need to work on...then someone texts you, hits you on Slack/Teams, emails you or taps you on the shoulder.

Nope! Go away. I am in surgery!
