Ask HN: What is your organization/note taking/brainstorming workflow?

I am astoundingly disorganized and have somehow managed to get 10-15 years in to my career without seriously addressing it, but my lack of process is starting to cause problems doing work. I've tried Obsidian but I ended up with a giant mass of unorganized notes. I've thought about trying to use Notion but I feel I need to see others' workflows before trying my own.

What does your workflow look like?
