Probably going through Rainer König‘s org-mode tutorial series on youtube. I like that it’s all with vanilla org-mode. That way you can dig deeper into anything he’s doing in the org-mode docs or on worg.

I don’t have a very rigid workflow with it. Typically one org file will be a project I’m working on. I use custom “TODO” tags to show the state of items. I also love the table functionality. It basically replaces spreadsheets for me and it lives with the rest of the text.
