Many people start internet marketing for various reasons. Some want a way to make a decent income that's easy. Some are willing to quit their job. Some just want to do it out of freedom. Whatever your reason is, you must consider it before taking action. If you really knew why you want to be an internet marketer then nothing would stop you from being exactly that.
The reason I got into this was to be successful. I don't know how you may define success but money is only a part of it. I knew there were others doing this and were making a good living at it. I wanted to be just like them. Plus it was something brand new to me and I wanted to conquer it. I also wanted to do it so I can have passive income. Passive income is money that's coming in automatically without having to work so hard. I work diligently but I really don't call it work because I actually like doing this. It beats being at a job I don't even like and working hard for the same amount every week or so. With passive income, there really is no "same amount".
So ask yourself. Why do you want to start internet marketing? If you don't have an answer to that then I suggest you think about it before doing it. This doesn't just applies to internet marketing but anything you begin to do. You might start a venture and realize that it's not for you and that's fine. But if it is for you then you will succeed because you'll stick with it.
