Do Not Disturb
In my opinion, async communication is one of the essential skills we should learn. Especially in a post-COVID time when many people still work remotely or on a hybrid schedule.
That's why when I sign up for a new social network, use a messenger, or set up a gadget; I'm always looking for an opportunity to hide my online status. And wherever I can set the status, it is always hidden or "Do not disturb." This is the first thing I do, really.
I don't want to give other people the hope that I will answer as soon as possible, and I never expect anything like that from others. Because 99.9% of things can wait while you are concentrating on what you are doing now. Don't let anybody distract you.
