Are there businesses and opportunities that are poor and where failure is likely because of the business or the opportunity? Sure. In fact the business, product, or market may themselves be the problem. However, significant experience and studies dictate that it is far more likely that the entrepreneur with proper mental clarity, dedication, and desire to make a living online could have made just about any business successful. 

Further, if they could not, a dedicated mentally tough entrepreneur would simply find another business or change their current strategies until they found a business or strategy that worked. Pointing the finger and placing blame gets you nowhere. So before saying “It isn’t working for me” or “This business isn’t going to work” look in the mirror and ask yourself "is IT suppose to work for me, or am I suppose to work for IT with a tenacity that does not allow me to fail"?
