Now, I'm a historian by training. Devotion to picky detail is in the blood. And since I am setting my story in a lost place -- 17th-century England -- I am "world-building." I am currently immersing myself in books about Stuart England, and in fact will be paying cold cash soon to get borrowing privileges at Northwestern University so I can get at their tomes.
And I can see myself just never coming up for air and doing research til I die. Or, if I do at last set pen to paper, I can easily see myself deluging my readers with everything I know about Stuart England. But instead, I have to tell a story. My subject is a true event, and I am determined to make it as historically accurate as I can. But the story has to take precedence to the masses of information that I'm storing up. When I write, I will have to have the whole scene accurately displayed in my imagination, and give to the reader just enough to get his bearings, paint the picture, engage the senses -- and that's it, let's get on with the story.
To be honest, I'm not sure that I have the capability of striking that balance.
