A non-virtual (AKA, "real world") fellow with whom I hadn't spoken in 2 months noticed the difference in my voice and outlook after a longish telconvo this morning. "How'd you know," he asked, "when you were going to make it?"
That was a very good question. I didn't have an answer, but now, as Miles Davis' live recording of "My Funny Valentine" comes to an end on iTunes -- something I could not possibly have listened to 2 months ago, and something which I was sure I deleted from my playlist -- I know what the answer is.
When I started to hear -- really hear -- and enjoy music again, that was when I'd crossed the Rubicon, that I was what Coach, as an old BUFF hand, will understand by the term "committed." There was no going back; I was on that path that exists for my steps alone.
