I think of pacing as making sure that important events happen frequently enough that the reader doesn't get a chance to quit reading. That doesn't mean every scene has a turning point, but every scene has to have some event that affects the overall plot, or that scene is basically "skippable". And every scene can help set up for a later turning point.
Here are a few quick tips for creating dazzling dialogue.
#1 Keep it short
Three to four lines between " ", then insert an action, change speakers, switch to a quick thought. This creates more white space, suggests more movement, forces you to be cogent and quick.
