Books are different every time you read them. Sometimes the time isn’t right to read a particular book; often there are many times are are right for that book, for different reasons.
The very best books, as you’re older and know more they become very different; for the most part I think they become much better.
Every time I seek to relive the emotion of a previous reading, I experience different and unexpected impressions, and do not find again those of before.
I start the review by re-reading some parts of my favorite essays of life advice. Different parts/essays every week. This also sometimes gets me to notice new parts of the essays that resonate or spark interesting thoughts.
