I think it would be a good idea to have a thread with general writing advice, tips and such. Some kind of collaborative effort where you add them to the OP. I've got this file in scriv I call 'bits' where I've c&p useful things from various books and places on the interwebs. Trouble is, I can't remember where most came from since I didn't attribute them since I had no plan to repost them at the time. Duh? And useful links!
I'll give you an example of something I kept, but I cannot for my life remember where the hell I got it, let alone who wrote it:
This sentence has five words. Here are five more words. Five-word sentences are fine. But several together become monotonous. Listen to what is happening. The writing is getting boring. The sound of it drones. It’s like a stuck record. The ear demands some variety. Now listen. I vary the sentence length, and I create music. Music. The writing sings. It has a pleasant rhythm, a lilt, a harmony. I use short sentences. And I use sentences of medium length. And sometimes, when I am certain the reader is rested, I will engage him with a sentence of considerable length, a sentence that burns with energy and builds with all the impetus of a crescendo, the roll of the drums, the crash of the cymbals—sounds that say listen to this, it is important.
So write with a combination of short, medium, and long sentences. Create a sound that pleases the reader’s ear. Don’t just write words. Write music.
Be nice if we could gather together such wonders.
