"Design a book cover for 'Unlock Your Life' with a shining, partially open ornate door symbolizing the path to self-discovery. The subtitle 'Awaken Your Potential; Reach Your Inner Greatness' is prominently featured. The cover should hint at personal growth and the unlocking of one's potential with a master key in the foreground, set against a backdrop of a sky hinting at dawn or twilight to suggest new beginnings and endless possibilities." con una mariposa y una llave
