Couldn’t have said it better myself.
A quote that could make all the difference in how you run your business… and how you manage your staff.
Twenty years ago, computers were productivity tools. Now, they’re distraction tools that kill focus, kill creativity, and kill our ability to do good conceptual thinking by providing a never-ending stream of irrelevant interruptions.
When a computer task crosses your mind, add it to a paper “computer to do” list that you keep handy. At defined, scheduled times of day, walk over to your computer and go through your computer to-do list. Treat the computer as a tool that you use consciously, take out, and put back. Don’t use it as a default location to distract your mind and attention. —http://www.steverrobbins.com/
(Emphasis mine. That list? The perfect accessory to any consignment, resale, or thrift shopkeeper’s outfit: a clip clothespin with your to-do list dangling from your designer outfit.)

I live and die by my lists and have one similar to your suggested ‘computer task’ list. I had to giggle though, when I read your post and the suggestion to attach your list to your outfit, I couldn’t help but imagine mine would trail along like a piece of stuck toilet paper. LOL Great suggestion and I appreciated the giggle too!
[Smile] Of course, lists need to be kept manageable too. I confess I have to-do lists dating back to 2014… and when I look at them I think “Huh. STILL a good idea…”
I know that when I see service people trolling their screens (phones included) when not actually dealing with people, I feel that they are not dealing with the most important component of their business.
Excellent analysis and excellent solution. Going to adopt this today! A very helpful post–thank you!
