Kind of a broad question. I wonder why people take notes - Is it for studies or learning? Is it just to remember things? Is it to make your own map of your knowledge? Is it because you just want a place to vent out your feelings into the void?
What do you use to accomplish that? App? Paper? A chat room?
I still takes notes at work meetings. Mostly so that I dont forget what was agreed or what I’m supposed to be doing.
Outside or work, I make tons of lists. I find them really helpful to know what needs doing and what needs prioritising.
Notewise, I use an old fashioned notepad + desktop stickies. For my life lists I use Simple note.
