How I Make a Full-Time Income in My Spare Time -- And How You Can, Too

As a young man, I learned how to make money online, initially to pay off my mother’s debt. I’ve used these same skills to create a lifestyle that many dream about, flying 96 times just this past year; living in such places as Johannesburg, Shanghai, Thailand and now Mexico, and speaking on stages all over the world.

One of the first products I promoted was “vertical leap” training to teach people how to jump higher in basketball. Then I started promoting potty training and erectile dysfunction products. Dog training is another lucrative market. Today, I’m in the business education niche, flying around the world teaching others how to start an affiliate marketing business themselves.

Next, define your audience. Determine who would buy this product and the pain it would solve. A great way to do market research is to look at the media kits of magazines and publications. For example, if you are selling a potty training product, the media kit for a parenting magazine will tell you the demographics of its audience. You can use that information to market to the very same audience. Another place to do research is in…
