You can’t plan this, that’s the point, but unexpectedly having a couple of hours in which you can’t do anything is great.
Today was timed to the minute for me with rushing everywhere except for one long meeting scheduled for 14:00-18:00. I then had to nip off to another thing for 19:00 and be back on a train for no later than 21:15.
Right now it is 20:24, I’m getting a train in a few minutes and everything is preposterously relaxed. The long meting wrapped 90 minutes early and we all went to a pub. I could stay, I did stay, I couldn’t go to my next thing for ages so I didn’t go to my next thing for ages.
I got maybe an hour relaxing and that on a day I was half dreading for how much I had to get done.
I still have a lot to do but I’m carrying on that preposterously relaxed feeling even as I do it.
So go on. Schedule your day tightly and then enjoy the cracks between than become chasms.
Mind you, I’m glad the train has mains power or it’d be a very boring ride home.
