Give me an idea how to get rich, and I promise that when I earn my first million, you will get 10% of it. At the beginning I promised 50%, but no one really believed.
How can you be sure?
Well, you really cannot be sure that I will give you 100K. But you have my word on it. If you give me a really good idea, and I act upon it and make a fortune, I think that you really deserve at least 10% of what I made.
