I like to say there are two kinds of writers. There are the architects and the gardeners. The architects plan everything before they set a word to paper, like an architect building a house. they draw up the blueprints, and they know deep the foundations will be. The gardener, meanwhile, digs a hole, and plants a seed, and waters it with his blood, and tries to shape what comes up. I think all writers are part architect and part gardener, but the proportions differ. I’m much more of a gardener than an architect.
