Sunday evenings are spent cramming for Monday deliverables – just like this one. That also includes doing anything (like this entry) to delay the things you should be doing (my output due tomorrow).
It’s been like this for a long time. I usually make plans to attend to things on a Saturday. Deal with the backlog and make some progress. That would be ideal. What’s realistic is dragging oneself from sleep on a Sunday evening to prepare a decent output for the next day.
There will be a lot of attempts not to do the tasks. Later, one would be content with having started something for the output due the next day.
