I also noticed that in your passive income chart at the bottom that you don’t include your internet income other than sales from your book. Is there a reason for that? Do you not consider is passive because you are actively blogging all the time to create it? Or do you just not want readers to know how much money you generate from blogging activities?
Passive income differs from active income which is defined as any earned income including all the taxable income and wages the earner get from working. Linear active income refers to one constantly needed to stay active to maintain the stream of income, and once an individual chooses to stop working the income will also stop, examples of active income include wages, self-employment income, material participation in an s corp, or a partnership.[4] portfolio income is derived from investments and includes capital gains, interest, dividends, and royalties.[5]
Some people are fortunate enough to create residual income streams. Residual income (also known as passive or recurring income) refers to income that you continue to earn even after the work required is done. Fundrise is the simplest and most cost-effective way for the everyday investor to create a new stream of residual income through real estate investing.

If you're looking to get started in real estate, look at a crowd funding solution like RealtyMogul. It works similar to LendingClub - you commit as little as $5,000 towards a property. When the property is fully funded, you become an owner, and will receive your share of the earnings and appreciation in the property.  Check out RealtyMogul to learn more.
