It’s interesting that we know and appreciate that there will be more work tomorrow and next week, but when you see it in advance, it pushes you to the bed.
One thing that [somewhat] helps me with it is breaking down the next thing into a list of pretty trivial tasks on paper, while leaving the rest at where it came from. Makes you focus on what’s here and now. Out of sight, out of mind. Doesn’t work 100% but helps a little if I manage to forget the rest enough.
