I am amazed at how my brain's ability to focus on long term tasks has been diminished over the past few years. I used to be a voracious reader, but lately have struggled to read (offline) more than a few pages at a time. I won't blame smartphone usage entirely, but it certainly has been a large contributor to that.
This year, I've begun a concerted campaign to reduce my phone time. The latest iOS screen time tracker ironically, has been a help. I look forward to the weekly reports that say "Your screen time has been reduced by x minutes per day". So far this year, the downward trend has continued.
I spent the weekend just gone reading a lot more, and also taking up painting again after a nearly 3 decade break from it.
