Context is essential for learning I recently was going back through a book I read a while ago, and I had highlighted some sections inside of it. Those sections were indeed interesting, but the highlight was mostly useless. Why had I highlighted those words? Did I agree with them? Disagree? Have other thoughts? There was no way to easily tell.
I use OneNote. My needs are simple and the app is universal on my devices.
I'm not a OneNote user, but it's a fantastic solution for a lot people and may can't live without it.
