I am not even close to this mark yet. But I still believe it is possible. There are many hubbers who openly disclose their monthly earnings through their articles. They also provide some valuable tips for you to get things done in the right way. You need to search for the top hubbers here and search for their articles on how to make more money through HP.
A combination of Adsense, Amazon, Hubpages earnings program and eBay will make this possible. You need to stay focused and keep on trying without losing hope.
