This is how you keep work life balance.
A unanswered phone is a happy phone and leads to a happy life. Anything which is important will be left as a message which you can respond after thinking on it properly.
An unanswered door is a happy door and leads to a happy life. There is no reason anyone with important information would be knocking on your door. They would have called (and left a message since you don't answer the phone) if it was important. If they don't have your number, then they are not important. If its important they will leave a note or shout through the door.
It's 2023, there is literally no reason to ever answer the phone or answer the door.
