Writing muscle

Last days have been crazy. My daughter started cyber school yesterday. I am determined that cyber school should not be an excuse this year. But already it has required my time, reading preliminary things from teachers, helping Maren gather electronic photos and documents she needs to complete homework.
So many things going on. I have not been sleeping. Up every night at 3am for the last ??? nights. I almost convinced myself that I would make that my writing time. But alas, last night was the first I didn't wake up. After I got my son off to school, I sat around starting to read a new novel. Something about the beginning sparked my desire to write. I was already dressed for my morning walk, so I decided to use the time to gather my writing thoughts. But once again, at home, I suffered interruptions.
I did get back to it, but the work is tedious. No flow. I fight every sentence I put down. I know that the only cure for this is to keep writing. I also know I am allowed to write bad things. I can go back and fix them when the book gets going.
Writing is a muscle. I just need to keep exercising it. I am going to be a little sore until I get myself in the groove.
