I shut and lock my door ten minutes before a meeting. Hit the bathroom and then usually log in for a functions check, fix my blinds and pull up the relevant group chat that doesn’t have the boss in it.

Organize my notes on my desk, get a coffee or water in front of me. Someone will always be later. I’ll sometimes be the first. Let teams let them see that I’m starting it, whatever, everyone knows I’m getting my coffee.

Also, I like to give my colleague a fifteen minute heads up since he’ll sometimes forget.
