That said, there’s plenty of good advice even if it’s a little inconsistent. It’s also fascinating how much the social part overlaps with challenges faced by Autistic people[1].
For ADHD folks who find some of the advice on multitasking/focus in meetings wanting: it’s absolutely okay to stim (perform some stimulating, often repetitive action) when you find your ability to stay focused isn’t what you need or what’s expected. I have a reputation for spending most of my time in meetings playing minesweeper. It’s not because I’m not engaged, it’s because it helps me stay engaged. I happily stop or mute my mic if the clicking sound is disruptive, but otherwise I’ve continually established with teammates and even clients that having that part of my focus on something mostly mechanical helps me stay in the conversation and productive.
1: Which I increasingly feel confident in the idea that there’s no meaningful distinction and ADHD should/likely eventually will be considered part of the spectrum, but that’s not why I’m commenting.
