The business executive was deep in debt and could see no way out. Creditors were closing in on him. Suppliers were demanding payment. 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 executive's woes, 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 business executive 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 erase my money worries in an instant!" he realized. But instead, the executive decided to put the uncashed check in his safe. Just knowing it was there might give him the strength to work out a way to save his business, he thought
With renewed optimism, he negotiated better deals and extended terms of payment. He closed several big sales. Within a few months, he was out of debt and making money once again.
Exactly one year later, he returned to the park with the uncashed check. At the agreed-upon time, the old man appeared. But just as the executive was about to hand back the check and share his success story, a nurse came running up and grabbed the old man.
"I'm so glad I caught him!" she cried. "I hope he hasn't been bothering you. He's always escaping from the rest home and telling people he's John D. Rockefeller." And she led the old man away by the arm
The astonished executive just stood there, stunned. All year long he'd been wheeling and dealing, buying and selling, convinced he had half a million dollars behind him
Suddenly, he realized that it wasn't the money, real or imagined, that had turned his life around. It was his new found self-confidence that gave him the power to achieve his targets.

She changed his world with a blink of an eye
That is something that he can never deny
She put his soul from worst to the best
That is why he regards her his dearest
It’s so magical those things she had made
To bring back his faith that almost fade
Now his life is a dream come true
It all began from the time he know her.
She still just doesn't know what she has done for him
She even pushed him to the best that he can be
She really is an angel sent from an above
To take care of him and shower the love
I wish I could talk 'til the end of the day
But now I'm running out of things to say
So I'll end by the line you already know
She changed his world with a blink of an eye
