Moral of the story

A Young Man asked a Rich old man how he made his money... 

The Old Guy said: Son! it was 1932.. The peak of the Great Depression

I only had a Nickel. I invested that in an apple & spent the entire day polishing it & at the end of the day I sold the apple for 10 cents. 

The next day I invested those 10 cents in two apples. I spent the entire day polishing them & sold them for 20 cents. 

I continued this 4 a month by the end of which I had accumulated a fortune of $1.37! 

Then my wife's father died & left us 2 million dollars! 

Moral of the story: Let me know if you find any.
