Of course, there's no guarantee of success if you happen to select one of the categories I'm about to give you, and it doesn't work on-line, things change and trends change very quickly on the Internet. But, Jeff Paul says in Shortcut to Internet Millions, these things are currently working and are currently being sold on-line, and we'll just give you a couple of categories:

•  Jeff Paul says in Shortcut to Internet Millions, one thing that is being sold on the Internet is communities. They are being built around topics such as Internet marketing, copywriting, fitness, buying and selling real estate, websites, antiques, press releases, beauty products, kitchen aids, automobiles, golf and self-defense. These things are all niches that you could go into and you could sell books, videos and audiotapes, and other courses in on-line chat rooms and things like that, and build basically a community around these types of things.
