He sat on the park bench, head in hands, wondering if anything could save his company from bankruptcy . Suddenly an old man appeared before him. "I can see that something is troubling you." he said. After listening to the businessman, the old man said: "I believe I can help you." He asked the man his name, wrote out a check , and pushed it into his hand saying: "Take this money. Meet me here exactly one year from today, and you can pay me back at that time." Then he turned and disappeared as quickly as he had come. The businessman saw in his hand a check for $500,000, signed by John D. Rockefeller, then one of the richest men in the world! "I can settle all my debts in a moment!" he realized.
