Find the hero in your story
All films are a variation on the hero journey, a motif of adventure and transformation that runs through all mythic traditions. Lord of the Rings, Harry Potter, Spiderman. The protagonist is always part adversary, part hero. His hero is born through self-achieved submission of the adversary. The drama is battling that which needs to be brought under submission.
Childhood is characterised by boundless potential. Run before we walk. Leap to level 10. Blind that each level along the way holds a gate than can only be opened from the inside. Carl Jung said the fool is the precursor to the hero. I see plenty of truth in that myself. So risk a hop, but don’t leap. Stay at the nest whilst you can. That desire to play a big role in your destiny comes with a price. The road of excess leads to destructive and addictive habits when it isn't under supervision.
Every single day is a death and a rebirth. So pick a time to be done. Fail at that a few times. Repeated failures compound until submission of the destructive habit becomes less painful than omission. Identify. Accept. Harness the adversary within you. You're done when you know you're never done with it. So don't wish away your past for a better destination. It's the scars along the way that make it a hero story.
