I'm not much of a fan of Peterson, although my lover has been. Still, I learned long ago, on my own, that sometimes I have to look at myself and do a little criticism. I learned, for example, that as much as I love things like single-malt scotch and good Irish whiskey, they turn me into something that I don't want to be. As a result, I simply stopped touching them. Love my beer, which doesn't have anything like the same effect, but you cand put a hundred free shots of liquor in front of me and I will just ignore them.
Much earlier in my life, I had to learn that the brutality of my childhood wasn't going to be an excuse for me -- that to get on with life, I had to accept that it happened, reconcile myself to the notion that those who hurt and rejected me likely had no more control over their lives than many of us seem to -- and FORGIVE them. That -- forgiving -- freed me. But I had to see it for myself.
