Someone commented recently on the free time I have now that I'm retired. On thinking about it, I realized that being retired is a full-time job. I'm retired every minute of every day of every week of every month of every . . . . never a vacation from this vocation.
Back in the distant days when I was working for someone else for money, I did not put 100% of my time into the job. My apologies to the several chancellors, deans, and provosts at Missouri Science & Technology during my time there. Once upon a time, a dean asked the faculty to account for the actual amount of time spent on each of our various activities. The faculty's response was, "Nope!" One can't tally the time one spends on teaching, doing research, advising students, and attending meetings. (Well, meetings could be timed but not the obligations that flow from committee membership.)
I'm certain that I worked more than 40 hours a week while I was employed. I won't even try to approximate the actual number of hours. But that — those tasks — are over. Yee! Haw!
Just remember, being retired is a full-time vocation. (Unh, vacation?)
