More simply: I'm pretty sick of productivity porn, and the empty promises it makes.
It’s procrastinating in a fashionable way to make yourself feel like you’re productive.
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.
Every other tool I've tried to use has been about 20x more effort than it's worth, and remembering to keep whatever-thing with me or to check it is harder than the entire rest of what I'm trying to accomplish with it. I always have my phone, and I don't need to check it because it'll scream at me when it's time for something. "WTF is that noise? Wait, what time is it? Oh shit, time to get so-and-so ready for practice!"
On the other hand, I have tens of thousands of words of text files in an Obsidian vault in support of my one hobby: game dev in Blender and Unreal. Workflows, gotchas, footguns, checklists. I have no idea how my middle-aged brain would remember how to, e.g. layer blend two materials after 6 months away.
This complex pursuit would be altogether impossible (for me) without my notes.
It's addictive, I can't lie. I would love to have a perfectly designed, neat workflow that captures all my tasks and quantifies my productivity with precision. The reality of work is that I already have to apply these principles to documenting things at my job. The last thing I want to do is to also need to maintain a perfectly manicured to-do list for myself.
Fiddling with my notion calendar of how many gym sessions/runs I made/missed is easier than actually going to the gym of course, but I like to think it helps me stay on track in a “what gets measured gets managed” kind of way.
But maybe when I’m older and more wise I’ll see it for the fallacy it is
