I love the romance of the '40s. It was the perfect time to live. Technology wasn't so advanced that it made life more difficult, but it was just enough that you can send a phone call or a telegram. And people still took pride in how they looked. The men got dressed up and the women got dressed up and they took care of themselves.
A lot of new writers assume you have to know the where the story is going and that it flows out as molten gold. But really, sometimes you think you are going to one place, but then you decide that is dumb idea. Then you go somewhere else and it is a worse idea. But then you switch again and you might have a beautiful accident.
