I love the concept of endless lists of lists. This abstraction can encapsulate almost everything in the world. Personally, I use 📝 Tana, previously used Workflowy. It works for me, maybe someday I will switch to Obsidian, but it does its job and I do not want to spend a lot of time tweaking it. One thing I love about it is the Capture app, where you can really quickly dump your thoughts.
Below is a random list of books, videos, articles, and more on various themes that I really like and wanted to share with you.
