Thanks Clint. I'll take a look at "Deep Work". My husband read your/this blog just now and we had a half hour discussion about working in the zone. He's a software engineer (hacker). He related very well to your description. It's interesting that you do your deep work at home. My husband works from home Monday's and Friday's and that's when he gets his best work done.
I'm working in a shared studio. It has worked well in the past, but now it's above an antique store and visitors come in all day, so it's more like a gallery with interruptions all day. I might have to rethink it. While writing, I need to be alone for about 5 hours. Thanks again Clint.
