Not exactly what you asked about but I remember when I was learning, I used to save every article I read in Evernote using their web clipper it was really easy and it felt good to have my own knowledge base. But I never looked into it, I ended up giving up on even trying to organize knowledge at all for years and years – I would take notes and create files to help with immediate things I had to do but I wouldn’t even bother with long term thinking about new subjects. This change very recently when I started hearing about the new linking notes apps, I started reading LYT Kit and not linking actually, felt too much, but at some point it clicked and reminded me that I had tried once.
It has been a couple weeks that I’m trying this new approach of note making so I don’t much to give other than: make your own notes with your own words otherwise you’ll just collect words that in the end you’ll not use or learn more than what you did when reading the words the first time.
