OKAY MOST BIG things we think of in the world today wal-mart Apple and so on were started small VERY SMALL……There is a gas station company in my state of MT that started small Town Pump and in now a major State corporation….The way to doing things is to simply sell things in a way people like or perceive are good and duplicate over and over again!!! My question is how DO YOU FIND THE WAY to sell things this way and how do you find OPPORTUNITY LIKE RICH ENTREPRENEURS?

I am interested in something for someone with no prior knowledge of the subject, and is considering starting a small business.
