Yes, it’s definitely possible to earn decent money online.  There are many ways that you can earn money, and it’s just a matter of finding your niche.  For example, you could create products like ebooks about a subject that you’re knowledgable about or simply like.  Then you can advertise and sell them. There are other ways too, such as affiliate marketing where you’re basically a vacuum cleaner salesman except you make websites and direct people to affiliate merchants, then earn a comission.  Affiliate marketing is very easy once you learn the basics, and a program like Profit Lance is a great way to learn.
