I highlight too much, how can I decide what info is worth highlighting and what isn’t?

Hello! This is actually a very common problem for students. In high school my teacher would make fun of me for highlighting my textbook to the point that the entire thing was yellow (or pink ). To fix this, I started a new tactic where I would read an entire section and not highlight at all until I was finished. I would go back to the passages I had read and highlight what I knew was important after reading! Although this sounds like more work, it was surprisingly easy to retroactively remember what was important and go back and highlight smaller sections. Also, I tried to keep in mind to only highlight "key words".
