When you are stuck in a book; when you are well into writing it, and know what comes next, and yet cannot go on; when every morning for a week or a month you enter its room and turn your back on it; then the trouble is either of two things. Either the structure has forked, so the narrative, or the logic, has developed a hairline fracture that will shortly split it up the middle – or you are approaching a fatal mistake. What you had planned will not do. If you pursue your present course, the book will explode or collapse, and you do not know about it yet, quite.
In Bridgeport, Connecticut, one morning in April 1987, a six-story concrete-slab building under construction collapsed, a woman across the street leaned from her window and said to a passerby, “That building is starting to shake.” “Lady,” he said, according to the Hartford Courant, “you got rocks in your head.”
You notice only this: your worker-your one and only, your prized, coddled, and driven worker – is not going out on that job. Will not budge, not even for you, boss. Has been at it long enough to know when the air smells wrong; can sense a tremor through boot soles. Nonsense, you say; it is perfectly safe. But the worker will not go. Will not even look at the site. Just developed heart trouble. Would rather starve. Sorry.
What do you do? Acknowledge, first, that you cannot do nothing. Lay out the structure you already have, x-ray it for a hairline fracture, find it, and think about it for a week or a year; solve the insoluble problem. Or subject the next part, the part at which the worker balks, to harsh tests. It harbors an unexamined and wrong premise. Something completely necessary is false or fatal. Once you find it, and if you can accept the finding, of course it will mean starting again. This is why many experienced writers urge young men and women to learn a useful trade.
