Now this is not necessarily the optimal strategy for sure, but for one reason or another my personality is better fit for this style. I read very few books but then "debate" it in my head, try to connect things to other things, life experiences, news, other books. Is it true what the author says? Have I read somewhere else that an implicit assumption the author is making has been discredited recently? What could be the motivation? Could I argue equally convincingly for the opposite view? What are the implications for other things I care about or was wondering about perhaps long ago?
For a long time I was very ashamed of how few books I read, compared to what is expected from an educated person, but I'm okay with it now. Same with movies. I watch a movie and I think about it for days. Just watching them for relaxation doesn't work for me, following who is who and what's going on drains me more than relaxes. Especially when there's no "payoff" and the plot can only be described with "and then they" sentences.
