My current system, the first one I actually like, is this:
Buy three-hole punched printer paper.
Write on it.
Everything goes into a single-three ringed notebook in chronological order, no exceptions.
When that notebook is full, take the paper out, put a sheet of brown cardstock on each end, and put brass fasteners through the holes.
That “book” then goes on a bookshelf, never to be looked at again.
