Simple Profit Machine

How can Simple Profit be Made? I think about this question every day and I sit around thinking about ways to make money on or off the Internet no difference to me. My one goal is to make a “machine” that will make money with very little interaction. It doesn’t matter how much upfront work it requires as long as once the project is complete, from this point forward it takes very little interaction from me in order to keep making a profit big or small doesn’t matter as long as it is in a way automated.

So the big Question is How does one make a Simple Profit Machine?
