Haha I'm so happy you have so much stuff to do, Kayube!!! I have a hard time keeping up with threads too lol (check out my plot tracker on Alphabet) but we'll manage it together somehow!
So, this is drawing from my experience~
Remember that you can always take a break! Also I'm sure your thread-mates will understand if you need to cut one loose or take a prolonged hiatus! Haha, and when you wrap stuff up and clean your plate, you can participate in SO MUCH STUFF, KAYUBE! >;D
I also recommend events that don't require continued participation while you're busy so you can drop off one post and continue until you feel pressured; just have fun and get a taste to see if it's too much for you! If it's too much, you can drop it. If not, you can enjoy the event! The world boss is dropping soon, so be excited for that too! :DDD
