Aqsa, the most important thing to remember about any kind of self-employed activity is this: "It doesn't matter how good you are if nobody knows you're there." In my case, I began by writing articles for magazines and then speaking at conferences. This all gave me some name recognition, so that as I came up with more products to sell, books, and so on, many people already knew my name or visited my website, so I could generate more sales.
