The real force here isn't wishful thinking—it's Goethe's insistence that self-belief is the *prerequisite* for action, not its reward. You don't succeed and then believe in yourself; you believe first, and that conviction changes what you're willing to attempt and how you'll interpret obstacles along the way. A musician auditioning for a symphony doesn't need to feel confident about winning; she needs to trust herself enough to walk into that room and play honestly, which itself opens doors that paralyzed doubt would have kept shut. Goethe understood that magic isn't about defying reality—it's about recognizing that your internal conviction is often the only barrier between you and the life you want.
