It is an experience only a retired person can understand. And I've got to admit that the first months of my retirement left me in an uncomfortable position. Routine had so regulated my life as a teacher that I began to miss it. But I found slowly that rather than being driven by routine and duty, I was now free to do whatever was at hand. I discovered that if you actually take the time to become sensitive to your environment there are always things to do or get interested in that you had not been aware of before.
People often observe that as one grows older, the days trudge slowly on, but the years fly by.
I find that not to be true, at least for myself. Yes, the years do fly by, but so do the days. Possibly that is because I am a writer. I work every day, and I find the work exhilarating. I know that I am fortunate in this.
