Premature optimisation is the root of all evil :) I was very much in your place a few years ago - the most flexible and responsive and useful place to have most planning is in your head: crystallising ideas and plans and all that just makes them brittle and a sharp failure point.

Most of these organisational tools are for multi-person orgs.

Your PKM should look very 'suboptimal' from the outside. You need much less conscious control than you're exerting. Let your system forget stuff.

It's infinitely better to have something completely undocumented than almost nothing extremely well-documented.
