How does following quote:?

Question

The only worthwhile literature is that which makes you think about your own life."

apply to the novel A Separate Peace by John Knowles

Answer 1

I haven't read this book, but I've just read a summary of it on bookrags.com, which is helpful.

When you read it, did any of the events make you think about your own attitudes to life?  If it did, then you can mention in what way and show that the book is 'worthwhile' in the terms of the quotation.  The topic themes in the book are envy, religion and war.  You could say if any of them influenced your thinking in any way.  If not, then ,perhaps the book doesn't live up to the quotation's benchmark.

You can treat it as impersonally or intimately as you yourself wish.  It doesn't need to be too soul searching to be a good essay - hope it goes well.
