Life is a Math Game - Joshua King - Bog

How did you do in high school math? Well, it's time to bust out those math books because life requires these skills.
The first equation you need to solve is your monthly passive income needs. Can you retire on $5,000/month in passive income?
From there, you lay out a plan to build passive income streams to achieve your goals. Some streams may be roommates ($2,000), dividends ($2,000), and blogging ($1,000).
Finally, you retire on passive income and keep building up your passive income streams. Simple math, right? You can achieve financial freedom if you believe you can.
