After reading this I might very well pick up the book he wrote about writing. This is pretty solid advice. Some I can really take to heart.
Stephen King’s Top 20 Rules For Writers
2. Don’t use passive voice. “Timid writers like passive verbs for the same reason that timid lovers like passive partners. The passive voice is safe. The timid fellow writes “The meeting will be held at seven o’clock” because that somehow says to him, ‘Put it this way and people will believe you really know. ‘Purge this quisling thought! Don’t be a muggle! Throw back your shoulders, stick out your chin, and put that meeting in charge! Write ‘The meeting’s at seven.’ There, by God! Don’t you feel better?”
3. Avoid adverbs. “The adverb is not your friend. Consider the sentence “He closed the door firmly.” It’s by no means a terrible sentence, but ask yourself if ‘firmly’ really has to be there. What about context? What about all the enlightening (not to say emotionally moving) prose which came before ‘He closed the door firmly’? Shouldn’t this tell us how he closed the door? And if the foregoing prose does tell us, then isn’t ‘firmly’ an extra word? Isn’t it redundant?”
Write for yourself is always good advice. When we first began to write… we wrote for ourselves. That is what we should always remember. If you are writing to market that is a mistake. Although I have seen people do it and read the horrible consequences.
