Don’t go into great detail describing places and things
This is one of Elmore Leonard's "Ten RulesTen Rules." I selected it from the list almost at random -- all ten are worth heeding. I love it because it's so counterintuitive -- you want to add color and detail to your story, right? No, you don't. You want to add story to your story, and just enough descriptive detail to bring it to life, which is generally a lot less than you would think. One brilliantly-chosen detail is worth half a page of description, no matter how beautifully it was written.
