First, for a writer, writing every day is akin to an athlete doing pushups. It is simply to work the muscles necessary for the skill. But for the skinny and spaghetti-armed, even a single pushup can be impossible. So such a weakling must start with something smaller, perhaps a pushling.
Second, Tolkien mentioned that the ideas for his stories simply sprang from “the leaf-mould of my mind.” Hopefully, this blog will generate some thick, rich mulch so that one day, little green seedlings of insight will push their way to the sunlight.
