25 years ago, after the failure of my first marriage, I spent a few months coming directly home after work and thinking about what had happened and why.
As difficult as it was to admit, I was responsible for most of it the carnage. Other people let me down, but I let them or enabled them. In the end, it all came down to me.
So I created a document called Doug's Happy Life, in which I described the future that I wanted. Over the years, that documented vision has guided my choices and my efforts. I am now living that life ... as a very different person. As Rocco very correctly suggests, you can too.
