The 48 Laws of Power

by Robert Greene

Casanova attributed his success in life to his ability to concentrate on a single goal and push at it until it yielded. It was his ability to give himself over completely to the women he desired that made him so intensely seductive. For the weeks or months that one of these women lived in his orbit, he thought of no one else. When he was imprisoned in the treacherous “leads” of the doge’s palace in Venice, a prison from which no one had ever escaped, he concentrated his mind on the single goal of escape, day after day. A change of cells, which meant that months of digging had all been for naught, did not discourage him; he persisted and eventually escaped. “I have always believed,” he later wrote, “that when a man gets it into his head to do something, and when he exclusively occupies himself in that design, he must succeed, whatever the difficulties. That man will become Grand Vizier or Pope.”
