I remember reading The Road Less Travelled, by M. Scott Peck, a long time ago. It dealt with issues of narcissism, addiction, self awareness, hard work, suffering, and growing into being an adult. Parts of it are out of date, and in retrospect, I can see that the book has some big flaws with regard to religion; but it also does a good job of exploring self-centeredness, and where too much can veer off I to unhealty behaviors. I think it might be a good book to add to your reading list.
