We went on a trip to Wisconsin for summer vacation and as a side trip, we stopped in Madison and visited a former professor of mine from when I was at Mississippi State University; he’s now at University of Wisconsin-Madison. We haven’t seen each other in thirty years, but we’ve stayed in touch on and off through that time (basically the whole time the Internet was being invented around us).
We had a great visit, and at the end of it, he said something that will stick with me, I think. He said he admired my persistence and always had.
That will keep me going for a while.
