Very true. However, for larger companies it's often very very hard to duplicate their methods due to the amount of money that they invest into it. I'm not going to lie to you and tell you that I make millions upon millions through AM or online. Heck, I'm not Jon

To be honest, my best month and what brought a smile to my face was the $200 and some dollars I made through Clickbank one month. That was amazing. However, when I saw that I spent around $300 to make that, I was a tad bit upset. I still don't have any methods to do it. I still haven't been successful, but I'm not going to give up.
The recipe for success is mostly your input. That topic that just churns out money and leads. Or that personal perspective that gives your visitors that "that sounds great, lets give it a try" attitude. The method that you need is your own. The traffic is the easiest to generate.
Traffic + Incentive = Profit, that's how I've seen it. Now I continue on my grind to figure out how to make that a reality. I've sunk probably 1000-2000 in AM so far for around 400-500 total return. It's fine with me, I've got money to burn. You know why I like Affiliate Marketing so much? Because anyone can get into it, but only a handful succeed.
Even the most "qualified" can try it and fail. I program in PHP/MySQL for 3-4 years, owned several web hosting companies, and been using AdWords and SEO for years - yet I can't succeed. It's a heck of a challenge, but you just need to keep trying.
Personally, I think I learn more from 1 on 1 coaching and case studies than anything else. The reason I joined WF was for the case studies - that and a knowledgeable community. That's what I'm about.
Just keep your hopes up and keep trying - but one tip that completely screwed me time and time again - don't quit on one topic unless it's complete. If you keep going for new ones you'll just lose money after losing money, and it is an endless cycle. Heck, that's how I lost a bunch of money in a month or so once.
Just take what you can from what people say. I'm going to go read the lightning round thread again.. I think that had some great info from Jon in there.
Good luck.
PS - Holy shit I wrote a book!
