> Now that I'm in my 40s, I don't care as much about recording information I encounter (other than for work). If it's worth knowing, I can look it up again. If not, ignorance is bliss.
I tend to keep a notes file precisely because it's such a pain to look up some things. If I want to know the exact set of qemu options that I want, for instance, I would have to piece things together from the man page, and/or try things from a half-dozen different blogs, most of which will be incompatible with each other or the version of qemu I'm using (in fairness, qemu networking options have changed a lot over time as they improve things; this might be an extreme example). Or, I could open my notes file, type /qemu<cr>, and grab one of a handful of commands that I already have composed and be done.
