Which rabbit holes should you explore?
Earlier, I went on a little rant about the proper way to explore rabbit holes . Except, there is no 'proper way'. Just do it your way.
Surely you're curious about something?
Let's plant some seeds. Things that might be worth being curious about. Some little ideas that might someday spawn a whole-ass rabbit hole or two.
This is not a complete list, or an ordered list. And it's definitely not a road map. You certainly can't explore all of these at once. You have to make some choices. Pick one and start exploring it. See where it takes you. See what you can create.
