A way to track optional goals, or activities that you value but don’t have deadlines or set frequencies. That would let you track how often you’re doing the sorts of things that help you thrive, but where doing any one of them is just as good as any other. For example, I might have ten activities that reliably keep me in a positive mood, and I want a habit of doing one or two from that category every day, but it doesn’t matter which ones I pick, and it doesn’t matter how often a particular one gets picked. It just matters that I’m doing something from that category.
