Sentences Need to Have Electrical Current

What I’m looking for is a balance between a natural tone—intimate, conversational, as you say—and the maximum amount of tension, so that I can keep the reader engaged. Sentences need to have electrical current. There has to be both tautness and flexibility, speed and slowness, as in martial arts, which I have done a lot of. You have to simplify sentences as much as possible while making them take on more and more complex subject matter. I like what Hemingway says—Like everyone, I know some big words, but I try my damndest not to use them.
