I’m a big fan of personal knowledge management (PKM) and I have a dog-eared copy of Building a Second Brain as proof that I’m deep into the idea. I teach the fundamentals of keeping a vault on a laptop, syncing core materials to a handset, and maintaining a public view of a PKM online. My online version is at https://publish.obsidian.md/transformation. Even though it gives away some trade secrets, I’ve created several professional links with like-minded practitioners of Open Education Resources.
