Mario Puzo, author of The Godfather, believed true love could be dangerous for ambitious people. In an interview while promoting The Last Don, he said romantic love can distract driven individuals, make them act foolishly and, most importantly, make them merciful. Puzo argued that ambitious people should have love only if they can keep it in its place. Yet he acknowledged that love can make life more satisfying. His observation reflects the tension between ambition, emotional attachment, sacrifice and personal fulfilment.
