So how do you have fun?
The first thing that I suggest to you is choosing a niche that you are interested in. People tend to worry so much about having the perfect niche (or the most profitable one), when the reality of success online roots from "understanding the niche".
If you hate sports, why would you try to promote it...because someone tells you it is hot? Knitting or Scrapbooking may be more your cup of tea. Maybe you like football, college football. Maybe you like everything about dieting. Maybe you like tractor trailers?
Smoking for crying out loud is a niche...so is stopping this bad habit!
So your step today is to write down 3 niches/industries that you are interested in and that you would enjoy writing about.
I am interested in #1: _________________
I am interested in #2: _________________
I am interested in #3: ________________
I will give you a second before I move on here, so grab a pen and paper right now and WRITE THESE down. This will be your starting point for implementing the Mad Marketing Method (MMM)!
If you are still banging your head against the wall at this point, I am going to give you a niche that I know well and that is a billion dollar per year online niche.
