in response to your self help book inquiry, it depends on what flavor you're looking for. the magic of thinking big: james schwartz, how to win friends and influence people: dale carnegie are popular ones, and they were helpful to me. but not as helpful as The Spiritual Dimensions of the Enneagram by Sandra Maitri. hands down the best book i've bought in terms of self help and im pretty sure you can get it off of amazon for like 2 bucks used.
