The last 2nd brain course started in November, you could email Tiago to see when the next one is happening.
How I use Evernote would be a good topic.
My basic flow is to capture any idea, write any draft, and capture photos of whiteboards or paper notes using Evernote.
That gives me a medium to keep track of everything.
When I’m using an app for the first time, I sometimes screen shot it and then write comments . . . you can see Red Hot Timer notes (Evernote)
I will say that I lot of notes also start on paper. I need to write out ideas, there’s something that a digital medium doesn’t quite capture when I’m thinking high level or big picture.
