Today was one of those days when I futzed more than I wrote. I could blame it on the fact that my husband had a medical procedure this morning that took up my mental space, or that I was having fun finding a new theme and format for this blog (which I’m very happy with), or that I had a mild headache most of the day. The fact is, though, I was simply “futzing around without producing any worthwhile music”… or words. I need writers’ beano to prevent the futzing. For me, writers’ beano often means limiting my access to email and other ways to fart, er, futz around on the internet.
I have an hour between supper and the time when our family is scheduled to watch a movie: I will turn off my email and browser, open a Word document, and write as though my life depended on it. Then I can go to bed happy.
