I recommend The Way of the Superior Man ( http://www.amazon.com/Way-Superior-Man-Spiritual-Challenges/... ). My roommate lent it to me after an ugly breakup. The title is a little silly (I certainly wouldn't describe myself as "spiritual") and I don't agree with every word of it, but after reading this book I finally felt like I understood women and relationships, and I met my now-wife a few months after reading it.…
I've just read half of it & I'll probably end up finishing it because it's so interesting. But I really dislike the implication that leadership skills (purpose, reliability, equanimity) are intrinsically male, while childishness is intrinsically female. At least now I know what type of women to avoid.
Thing is - and this becomes more clear in his other books - men and women both have similar skills, but both have a TENDENCY to feel more comfortable in a specific skill set.
So, on the one hand I love Deida's advice. It is oftentimes on the spot. Very clear and even actionable at times. But on the other hand, it oftentimes is also too abstract, too simple, or too black-and-white. It almost feels like he's describing his favorite action movie star and if you read it that way, you can get the impression that he describes film heroes (super clear purpose, cannot be distracted, live on your edge). While a film hero can be an inspiration, it is oftentimes still a heavily simplified character.
