Buying leads looks obvious until somebody asks where they came from, and that question runs through the best posts here. The answer is usually that a name and address were collected for something else entirely, sold on, and sold again, which is why the response rate disappoints everybody who tries it.
Those lead posts have a different voice from the rest of the blog: looser, chattier, full of folk and tiny else to it. They argue that this business consists of contacting people, building a relationship and asking for a decision, and that the hard part is the middle one.
Everything else is standard tips material in enormous quantity, on network marketing, affiliate promotion, article writing and home business, with no shortage of repetition.
There are also two links to well known personal development material offered without comment.
A hundred and thirteen posts. Find the lead generation ones, read those four or five, and use the rest as a search index rather than as reading.
