People who are successful in a certain niche aren't going to share it here. Sharing your strategy for making money just means more people copy your plans and the potential revenue you can make decreases. If you want to make money - TEST, TEST and TEST. That way you will have built up the research and probably carve out little areas where you can profit.
Unfortunately this is the case... no one is going to help you. All those gurus selling seminars, courses and books aren't selling any step by step guides in how to make money online, they are all making money off those sales, and maybe some actually had success but they are not going to tell you exactly how, they just give some basic guidelines that will not make you money, you will learn something, but making money means testing and having luck.
This! If they're successful enough to earn a lot of money, they wouldn't bother with those seminars. And even if they really are generous enough to share their experience in those classes, what worked for them may not work for you because of different and changing circumstances. It'll really boil down to patience, knowledge and some luck.
