Scenes must move.  For your main characters, each scene or chapter should be a sheer slope or a plunging ravine in their emotional rollercoaster.  Positive to negative for one scene, reverse the polarity in the next.

If you have a scene where your character feels exactly the same at the end of the scene as they did at the beginning, with no peak or trough in the middle, chances are it’s just exposition.  Change it or delete it.
