I have been lucky, true... though not as much as I might have made it sound. I've also spent years building up friendships and exchanging favors with other authors. Like the times I shamelessly beg to beta <g> Still, there are times I can't get anyone to look at my stuff, for one reason or another -- and I never just assume that people are going to want to help me with the next story, just because they did with the last one, so in a sense, I'm starting from scratch each time.
Forgive me if I'm not coherent -- my daughter started running a fever last night and threw up about four or five times overnight. So I'm sleep-deprived and distracted by a cranky child.
