Character motivation is an important one.
Without your character having something that is motivating them, something that is heavy on their mind which may then spur them towards acting in a certain way, then you may as well leave them out of your story. A good tale does not need passengers.

But, what kind of things can drive your character forward or be a topic they are focused on?
