The same video showed up on my feed last week. I didn't try wall staring, but I did try a day (last Tuesday) with only a single screen active for the entire work day. I was extremely productive that day... but, and I know this is bad, I don't want set expectations too high. So here I type to you on a screen / device that should be turned off.
I went from a single monitor setup to triple monitor a decade ago, and then back down to single monitor.
It helps me focus to have just one active “feed”. And I put my phone away when I work to eliminate that screen as potential distraction.
Where I still kinda “fail” is during natural downtime. Like if I’m waiting somewhere, e.g the Dr office, I’ll pull out my phone and browse mindlessly.
