Awhile back (on May 25th, actually), Shirley Jump blogged over at Romancing the Blog about time management vs. setting priorities. She made the point that finding time to write isn't so much as finding time as making writing a priorty. If it's a priority, then you'll find the time. If it's not, you won't, and all the time management tricks in the world won't make a bit of difference.
Yet I also appreciate that for unpublished writers, it's difficult to explain to non-writers why producing what seems like nothing is so important. Once you sell, people are a little more impressed because hey, you get money! But until that day? Not easy.
But nobody expects a beginning sewer to turn out a lined, fitted suit with perfect button holes for a first effort. They appreciate it's going to take time to learn the techniques, what fabric works best with what sort of pattern, etc. etc. It's like that with writing, too.
Maybe unpublished writers should say, "I'm learning how to write a novel" when somebody asks what they did on the weekend.
On the other hand, I suspect the response would still be, "Oh, I'd like to do that, too, if only I had the time!"
