Let me put that notion to rest right here and now. Yes, some people have come online with just the right product at the right time and made it big rather quickly, but that in no way means they didn't take a lot of preparation to get to that point. AND it doesn't mean that this happens for everyone. Most internet marketers start out online with a little traffic and a few sales, then they aggressively and constantly apply the necessary techniques to build their business every week. Most start out part-time and build their incomes up until they make more money from the internet than from their regular jobs.
Most marketers actually fail at first in their businesses.
You are only a failure if you give up and quit after you fail. Way too many people I have spoken with blamed their failures online on the market. They went away saying the internet just doesn't work. I am here to tell you it does work, if you know how to work with it. You should see my shelves in my home office.
