In "Shopgirl," the contrast between two characters highlights different approaches to desire and thought. One character embraces simplicity, acting on desires without letting them become overly complex. This straightforward mindset allows for freedom and spontaneity in pursuing what they want.
In contrast, Mirabelle's tendency to overthink leaves her ideas trapped, unable to evolve. She gets caught in a cycle of contemplation, which hinders her ability to act. This dynamic between the two characters illustrates how overthinking can distort and immobilize one's true desires.
