Grassblades is pretty much constantly on my mind in one way or the other - toying with ideas to include, tinkering with the outline, weighing the pros and cons of certain storytelling choices, designing characters, trial-running dialogue in my head, etc., etc.
... But I kind of get like this with all of the things I'm doing. My mind is constantly tinkering with ALL THE THINGS at once. When I'm working on Grassblades, I'm ALSO coming up with ideas for what to do for my Christmas-calendar-oneshot for this year (yes I know it's only February shh), picking at a bunch of other ideas that might become bigger, long-form comics at some point, doing illustrations on the side that somehow magically grow into themed projects (like my Tea Witches, and my Goblin Week-entires every year), thinking about cool stuff I could do if I ever got around to teaching myself the basics of how to make games or animate things properly, etc.
... not to mention just randomly telling myself stories with the cast of literally hundreds of characters I've made up just for fun, who will most likely never have comics of their own, because they're just my equivalent to singing in the shower, or a bedtime story - they're just a way for me to unwind.
I have a very busy brain. >.<
