Body Doubling

For some tasks it is trivial, just providing the motivation. Other tasks that are more complex benefit from the whole "two minds are better than one" situation.
I want to combine it with brunch, another regular event of ours. It would be nice to start the day with a lavish breakfast, before everyone settles into their work day. I have a bit more free time, and it would make me really happy.
So basically just work at a company in an office and you'll be more productive.
Literally company
Nothing has been anywhere as effective as sleep, nicotine patches and (prescribed) ritalin. But having someone actively working near me (even my daughter doing her schoolwork) does help a lot.
For example if someone emails me an issue saying "that invoice software you wrote has a slight miscalculation" instead of taking me ages to work up the ability to even start working on the issue never mind trying to calm my mind to go through the data logically - if i'm having a manic adhd day - I will get the person to pop along and we can go through the issue together, this helps my brain immensely.
Even at home now if I have something urgent to do, I'll get my mum or a friend to pop round and sit and chat with me while I do the work - whether it's the laundry, or laying turf in a garden.
Otherwise I'll procrastinate until it's (almost) too late yet feel guilty every second of the time I'm not doing what I need to do.
“Misery loves company” comes to mind.
The difference between body doubling and "working in an office setting" is mutual agreement to avoid distracting each other. I usually combine body doubling with a pomodoro timer, so 25-30 minutes and then a break. This isn't conducive to deep flow work, but it's great for getting your taxes done, booking a trip, researching a dreaded thing, reviewing a PR, etc.
