I also love having a to-do list. I have a Google Sheets document of all the things due and when, and then I organize it by deadline in each category (classes, Dungeons, HOLLERS, Misc., newsletters, The Sett, teaching.) The feeling of checking something off really is quite awesome! Then i highlight the object in green once i've received points for it so i can check at the end of the month/term/year if there is anything missing.
While I'm actually studying/doing work, I also like to listen to music with no words (at least none in English) and I need to be sitting at a table or my desk because if I'm on the couch or somewhere comfy there's a good chance I'll fall asleep!
