To Make Writing Both Interesting and Original
C. S. Lewis is perhaps one of my favorite authors. He wrote Chronicles of Naria (which I love. Don’t go after the recent movies.) and The Screwtape Letters are very good. So it makes sense that I would eventually quote him here.

C. S. Lewis
Don’t use words too big for the subject. Don’t say ‘infinitely’ when you mean ‘very’; otherwise you’ll have no word left when you want to talk about something really infinite.
— C. S. Lewis
Even in literature and art, no man who bothers about originality will ever be original: whereas if you simply try to tell the truth (without caring twopence how often it has been told before) you will, nine times out of ten, become original without ever having noticed it.
— C. S. Lewis
