Next week, my guitar playing has been again requested at mass. I still need to pick out the songs, let alone practice them. I have time, but often I use that as an excuse to continue to procrastinate. I want my playing to be better than "good enough," and that requires practice.
The same is true for my teaching. The courses that I am teaching this term are all courses that I have taught before, but it has been years, from two years to nearly a decade, since I have actually been in the practice of teaching them. Like my guitar playing, I need to review these lessons, pulling from both "songs" I know while still trying ones that are new.
The truth is that I feel a bit rusty, and I am concerned about letting people down. Actually, that's not quite right. Rather, I want to perform well to live up the reputation I have gained so that people don't think less of me. It's a more selfish reason, but one that gets me to practice.
