My hyper-focus is so evident that when I used to work in retail, a sort of New Age hippy boss I had, when complaining to me about not multi-tasking and spreading my attention in the store, put it nicely by starting with: "Your intense focus on only one thing at a time is very Zen.....but....."
What had happened was we were suppose to be responsible for not just serving customers, helping them find something, ringing up purchases at the register, but also for gift-wrapping -- at a station where your back is turned on the rest of the shop!! -- plus also taking stock, arranging displays, going getting new stock from the back. All this while ALSO keeping an eye on all customers.
This was before security cameras were universal. It was a small mom-and-pop store so old fashioned eyeballs were the order of the day.
Well, some kid who turned out to be a well known petty thief in that area, stole a watch from a display cabinet while I was the only clerk on duty in the store and was busy with a customer --- I probably was turned around standing there gift wrapping at the time.
I got blamed for not keeping an eye on things, and because my boss had already noticed that I tended to be able to pay attention to only one thing at a time, I got hauled over the coals. I've never been able to multi-task, and when I try it feels like a big fuzzy ball of stress is building and building until I can't take it anymore.
