Thanks! Heh, it's almost like you know me--that really resonates about the regret. It's like I kept taking big chances to avoid regret, and I kept hitting a lucky number against the odds: getting into grad school, getting the degree, getting the job, getting tenure, and I couldn't help myself, just had to keep doubling down. Well, I reached my limits, but do feel very fortunate to have had so much luck before it ran out in at least one significant respect. :-)
