Writing around family life

I did not think to start writing until my children graduated from high school. At first my husband was bothered by the time I spent writing, for this was time I could spend with him. He'd interrupt by asking me to find something for him. He'd call out that I should come look at something or ask outright when I'd be done.

Then our youngest daughter went to film school. Financially vested, he picked up screenwriting protocols and shooting techniques. He watches independent films, and can now debate plot arcs and character development. He notes inconsistencies in sun angle, cloud cover, seasonal leaf color. (He'd be a great script supervisor.) He guesses locations--and is often right.

But while he can be a paper tiger, I am responsible for claiming--and maximizing--my writing time. As a prepublished author, I need to set internal deadlines. I have not yet set whether these should be scenes or targeted word count, but I am figuring it out.
