I actually saw a bit of his appearance on Oprah when I was at the gym. I thought he enjoyed recounting his screwup stories a little too much. He seemed strangely proud of them. And now it turns out he's proud of his lies.
And from what I've read about the book, it's astonishing to me that anybody would believe these stories in the first place. They're not even halfway credible, particularly the nonsense about the girlfriend he met in rehab who killed herself because she couldn't wait 12 more hours to see him. Gimme a break.
The hallmark skills of a substance abuser is lying to and manipulating others. I have seen too many who hang on to this part of their life even after giving up the substance abuse.
Your life ain't straight if hang on to the lie and the con. Oprah and this goof display similar traits (Oprah with a much smoother delivery).
