More often than not, heroes make bad choices, and it is this which drives the story forward as now the hero must work to extricate himself not only from the vagaries of chance, but from the burden his own poor decisions have placed upon him. Pinocchio sometime and count the numbers of bad choices this character makes. No, he invites the vamp with the nice rack instead.

Scenes always have goals.
They must advance the plot, or shed light on a character, or give important background information, or set a mood, or spur a decision. And so on. Note that not all scenes have to lead to decisions, either. Sometimes you're just establishing stuff the reader should know. Make sure you have a real goal for every scene, and then put it across.
