The best cure for it is, reading.

Beginners’ failures are often the result of trying to work with strong feelings and ideas without having found the images to embody them, or without even knowing how to find the words and string them together. Ignorance of English vocabulary and grammar is a considerable liability to a writer of English. The best cure for it is, I believe, reading. People who learned to talk at two or so and have been practicing talking ever since feel with some justification that they know their language; but what they know is their spoken language, and if they read little, or read schlock, and haven’t written much, their writing is going to be pretty much what their talking was when they were two.
