I have an evening full of plans, thankfully. Cooking dinner, walking around familiar streets outside. It happens to be a really nice day where I am, so I want to take advantage of that. I really suggest a walk or light exercise. I walked for at least a half-hour this morning, and I felt a lot better after realizing that results might very well come out super soon. I also have some paints and cheap, small canvases I might use (I am no artist, believe me.). Finally, I like to write haikus. Maybe I'll come up with a silly and lighthearted one for today.
That's just me though. Before the evening hits, I'm just watching/listening to some YouTube videos that make me happy. I was just listening to Queen actually.
Hopefully this helps/I'm in a somewhat similar boat--and good luck with your paper!
