I think the author means well and I think his story of going from dead broke to millionaire in 5 years is awesome. As he mentions, he did that with some sacrifices, including personal relationships. I wish he would have spend more time digging into this and its importance, as I feel like many people struggle with this. I think it's a great book for him to tell his story and what worked for him, but I think he should leave the financial advice to those that are much more familiar with how this stuff works. If you're looking for a similar book, but much better, I would recommend Set for Life by Scott Trench. For those interested in real estate, the section in this book on real estate is generally weak in my opinion. I agree with the author's position on putting less than 20% down in certain situations - his examples of why on this are right on. In general, though, I would suggest checking out BiggerPockets for in-depth real estate investing info.
A more complex system, pay per lead affiliate programs compensates the affiliate based on the conversion of leads. The affiliate must persuade the consumer to visit the merchant’s website and complete the desired action — whether it’s filling out a contact form, signing up for a trial of a product, subscribing to a newsletter, or downloading software or files.
SkimLinks works very similarly to VigLinks in that it is designed for bloggers who don’t want to do a lot of hands-on work to participate in an affiliate program. SkimLinks also works much like VigLinks in that it uses a plugin or script to create dynamic links in your content to send visitors to higher paying offers from merchants. SkimLinks claims to work with over 24,000 merchants/advertisers.
Statistically, if you want to guess who is going to be wealthy and financially independent, you'd be more likely finding a self-sufficient student in wood shop class who paid for his own car, gets decent (but not spectacular) grades, has a job and enjoys what he does than selecting someone from the honor roll. It's counterintuitive, but it's often true.

If the world truly is against you to the point where the entire market is upside down, or the world is going crazy, you can’t be sure your assets will remaining with you. I always tell people “If you’re index investing or properly diversified in the entire world, I’d argue you’d have bigger problems if your portfolio went to 0, like where and how to get food”

The concept of affiliate marketing on the Internet was conceived of, put into practice and patented by William J. Tobin, the founder of PC Flowers & Gifts. Launched on the Prodigy Network in 1989, PC Flowers & Gifts remained on the service until 1996. By 1993, PC Flowers & Gifts generated sales in excess of $6 million per year on the Prodigy service. In 1998, PC Flowers and Gifts developed the business model of paying a commission on sales to the Prodigy Network.[8][9]
