If you want to make it, don't buy into any "systems". Maybe invest in an established website on DP, that'll give you a steady stream of income and an understanding of what makes a websites work.
As for adwords, you can make money. If I can make money, any moron can make money. You just have to be creative, and put 100% into the campaign. That means multiple landing pages, testing thousands of keywords, testing ad variations, promoting different products, split testing offers across networks, and tracking everything.
There is no "easy way", but compared to bagging groceries or putting shingles on roof tops, I've got the easiest job in the world. I work my ass of to make it happen though.
