I've come to the conclusion that writing a novel and talking about it with friends is like building a boat.
At first, the builder is so excited about his project he tells everyone, and kind listeners tolerate his prating on until the builder eventually begins to realize that perhaps only other boat builders are the ones interested in his misadventures.
Over time, the boat builder realizes that saying nothing is the best course, until the time comes when perhaps someone who expresses an interest in his project stops by for a look.
The boat builder eventually reaches the point where all his efforts must be focused on the boat, and that sharing it with others is time lost, with the exception of sharing some of his trials and tribulations with other boat builders, who offer excellent suggestions.
The boat builder knows that someday soon the boat will be ready for deep water and if all goes well, a christening will be a welcome. It is that moment the boat builder has firmly fixed in his mind. Everything else is the journey getting there.
