Do you "supplement"?

I enjoy reading, but the books I like to read I tend to find challenging. So while I am reading or after I have finished a novel, I’ll also look online to see what other people have written about it. If there is a Sparknotes entry on the book, I’ll read the chapter summaries and analyses, to see if there is anything I missed or symbolism/themes that I didn’t pick up on. I think doing this helps me engage with the story better.

Do you think this is a good reading strategy? What strategies do you use to be a better reader?
