If you already have an existing business, you can choose to expand your market by selling your products and services online. This opens your business to a wider range of consumers, both local and international. You may also opt to start a new business online, and start advertising on your site.
If you do not know how to create a website, or do not have the time to do so, you should consider checking out certain sites that specialize in selling and auctioning different products. Sites such as E-bay allow you to make money by selling an extensive array of products, both old and new.
"Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do, so throw off the bowlines, sail away from safe harbor, catch the trade winds in your sails. Explore, Dream, Discover." - - Mark Twain
