I'm not smart enough to understand what I just read, but I've been using OneDrive for years. I have a notes file for each week, and tag each thing I write down. I also have a traveling notes file, for projects that are new, in progress, and expiring.

Accessible from Win, Mac, Linux, iOS and Android. Nothing to install or maintain.

When bored I might open the third week of March 2018 and see what I was interested in, and my mindset.
