Some people spend years in Zen meditation to reach what the professor has attained at the end of a school year: An empty mind.
My brain is empty. I am no longer looking forward to the end of the year — it’s just there. Next week I will sit in office hours looking at my gradebook and giving exams. I will grade the exams. And then I will be done with the semester and … nothing. My mind will consider “What’s for lunch” an unsolvable calculus. My only emotion will be relief. If I even have an emotion; many times I just sleep for 23 hours straight.

I’ll have a week of numbness to get over the oncoming train, which is the end of the college school year. Not so much mindfulness as mindlessness.
And then there will be summer semester and 20-some interns to supervise. But at least my days are more relaxing most of the time.
