Now, while there are plenty of books out there on business building, online materials, articles, and such, so I won't go into detail here. But I do suggest three options for you:
1) If you have something your passionate about and you want to build a business around it, find someone who has business expertise who you can partner with. This will help you prepare vital documents, but it will also help you in the negotiation process - high financed people have a tendency to want to deal with those who operate in a dispassionate manner, but your best creative ideas come from your passion - your business partner will be the person who can give potential financiers what they want.
2) If, on the other hand, you're the one with business expertise, find someone who has something they're passionate about that you can turn into a marketable product. A business needs to be built around something, and if it's something one person can get excited about, it's more likely others will get excited about it as well.
3) The third option is to partner with a franchise. These have done all the research and development for you, and all you have to do is promote the product(s) or service(s) to others. Many traditional franchises are too expensive for the average citizen, but thanks to the internet, you can find a franchise that is easy to run with low overhead and that can even be operated on a part time basis around your current job, if need be. You can find a list here.
This is the first step. Once you have your business up and running, then you can focus on expanding it to build prosperity for yourself and others.
