Let me tell you how I became a millionaire:

First, I bought one apple for a dollar with my savings.

Then I went out on the street and sold it there for two dollars.

With the two dollars I bought two apples for 1$ each and again sold them for 2 dollars each.

Now I had 4 dollars and was able to buy 4 apples, which, you may have guessed, I sold for 2 dollars each.

Now I had 8 dollars and I bought 8 apples and so on and so on...

A few days later my aunt died and I inherited her assets.
