Apt, part 2

In reponse to the post below about movie titles that best describe my days, a reader writes:

Thinking about a title for your movie is interesting, but who to cast even more, maybe? Who would you like to play you?

Back in December, I was interviewed on a British blog (one of those "know your blogger" deals) here. If you click, you'll find my reponses to many questions, so don't. In any case, there are so many, that you surely wont even get to the pivotal one, toward the bottom, where I was asked this and gave the following answer (greatly improved, btw, by the superb editing job of a fellow blogger):

Q: Who would play you in the movie about your life?
A: No one who is already famous. Instead, I would be the breakthrough role for someone who looks smart and irrepressible on screen.

Also interesting on that List of Questions was the following, as well as my response to it:

Q: What is your most treasured possession?
A: Absolutely nothing material. My memories.

I wrote that before I knew I would be sifting through posessions in the summer ahead and letting go of so many of them. Why is it that we always sound so arrogantly confident in making statements about matters with which we haven't had much experience?
