Velocity of circulation

It can only be called a pipe dream. It has always been my desire to invest a sum of money and once I get sufficient returns, and take out the initial investment before it is too late. The returns will continue to earn money while I invest that amount in another fund. And then when the second fund starts giving good returns, I again take out my initial investment and allow the returns to continue earning for me, while I invest the original sum in yet another fund ... you get the idea; the faster I circulate my original money from one fund to another, the quicker I become rich.

This would be ideal. But I have never been able to do so. Perhaps I lack the discipline to follow it up.
