My First 20,000 Days

I just stumbled across the fact that I had better get cracking if I want to publish a book entitled My First 20,000 Days by the time I reach that milestone. Twenty thousand days translates into 54 and three quarter years, which is just a shade more than 3/4 of a year from now. Let's see, what subtitle might I assign to the book? Memoirs of a Moron. I don't much like the sound of that, but it may fit.
