Wonderful tips. I never thought of 2 that way.

What I love is spaced repetition of the highlights. I don't do it time based though. I do it based on subject, and this gets a lot more powerful when it's more than one book on a subject.

For example - go through my highlights on Influence (Chialdini), Thinking Fast and Slow, Poor Charlie's Almanac, and think about how they complement each other.

Seeing the same subject from multiple points of view, sometimes conflicting, other times corroborating each other is very helpful to build a more wholesome base of knowledge.
