A couple related suggestions: - https://www.amazon.com/Seeking-God-Way-St-Benedict/dp/081461... - If you're religious, this book is great. If you're not, I think you can still take away from it the values of balance in life, being open to life's changes, and doing daily routines with love. - https://www.amazon.com/Seven-Storey-Mountain-Thomas-Merton/d... - It's meant by the author as a sort of confessions for the 20th century. Also, Merton lived a pretty interesting life, so it's an entertaining story from that stand point.

Generally, what I've found is that most helpful introspection books say a lot about getting out of one's own head and focusing on one's relationship with others (and, for the religious, one's relationship with God).
