I think there’s immediate gratification in this. You feel like you’re making progress towards your goals by planning them out, even if you don’t actually progress. You just add a superfluous step of documentation and complete it. A small industry has formed around this feeling.
I think one can achieve a lot in life with much more rudimentary planning tools, like pen and paper. I am yet to find a situation where that doesn’t get the job done for me personally.
Check out Hobonichi. It's a whole cottage industry dedicated to making your notebook/planner look nice. I like looking at the designs, but, like most people, I never have a need to re-open notebooks, so there's no point in trying to convert my idea scratchpad into art.
