I found this quote from James Patterson from an interview he did for Fast Company. It helps me a lot.
Outline Like Your Book Depends On It (Because It Does)
I’m a fanatic about outlining. It’s gonna make whatever you’re writing better, you’ll have fewer false starts, and you’ll take a shorter amount of time. I write them over and over again. You read my outline and it’s like reading a book; you really get the story, even though it’s condensed. Each chapter will have about a paragraph devoted to it. But you’re gonna get the scene, and you’re gonna get the sense of what makes the scene work.
