Yeah, that happened to me this week. I taught a class for our local library on the fundamentals of good fiction. I tore through a huge list of topics - characterization, pace, show vs. tell, dialogue, etc. And apparently developed a brand new favorite phrase - 9 times out of ten. I have no idea why I felt the need to say it repeatedly. It isn't a phrase that comes up often in my normal life. Honestly, it wasn't even that important in the topic I was covering.
And, yet, I heard myself say it over and over again. To the point that I was aware of it and by the end was cringing internally every time I said it. But I couldn't seem to stop myself before the words were out of my mouth.
So what does this have to do with realizing I missed a great opportunity? It wasn't until later that night when I realized I could have used the situation in the class. At one point I even talked about ways to tighten your writing - like looking for repeated information, words and phrases. Duh! Like the one I kept repeating endlessly.
I'd really like to go back and edit my class. Unfortunately, without a time machine I don't think that's going to happen. Ever wish you could go back in time and change something you did or said?
