1. What is your character desire?
2. What is your character fear?
The dramatic tension in the story lies in the contrast between desire and fear. Something or someone must stand in your character's way otherwise there is no conflict, no tension and therefore, no story.
Your reader wants two things - to identify with your character and to escape from their own reality. So, from the outset, tell us what the character wants to achieve. That is our hook into the story. Now, keep the character focused on this objective. Nothing else matters. A mistake might be to allow your character to move aimlessly through the action, only reacting to events. If this is the case, then you are in danger of losing our interest.
So, force your character into action. And the more extrovert they are, the better. Extroverts just can’t help making a fuss!
