And real estate does more than just track inflation – it throws off income (which is important to some people and useful to most). And while your underlying asset is appreciating, the income also grows as rents increase over time. And if you make smart and well-timed purchases, both rents and asset values can increase at well above the rate of inflation.
ie first you need to haul ass and do something crazy, eg write a quality 20,000 word ebook (insanely not passive hahahah), but then you get to sit back and enjoy seeing PayPal sale messages pop up on your iPhone each morning as sale after sale after sale is made…on an ongoing basis and without any additional work. That’s some seriously Pina Colada flavored passive goodness!

If you’re familiar with the phrase “don’t put all your eggs in one basket,” you know that it applies to just about any area of your life including—and especially—your finances. In addition to retirement becoming an ever-elusive goal, no one has guaranteed job security so by diversifying your income you can feel more secure about saving for your future. You’ll be less likely to find yourself in credit card debt and happier as a result of being financially secure.
6. Network Marketing: Network marketing is a unique business model and has made more millionaires than any other business. The industry as a whole is growing and more companies are trying to leverage referrals or direct sales to increase revenue and market products. However, the industry as a whole is confusing to most and requires a tremendous amount of mental and emotional fortitude to make residual income possible. Furthermore, the sustainability of that income vs. the effort you must put in is important to consider.
While residual income can be used to describe the amount of net income after all costs are paid down, it also refers to the amount of money you continue to generate after your initial work is done. There are countless ways to make money, but some are much more time-intensive than others. Active income, for example, refers to when you directly act or perform a service for money, including salaries, wages, tips, commissions, and income from a business you’re actively involved with.

Residual income is the amount of net income generated in excess of the minimum rate of return. Residual income concepts have been used in a number of contexts, including as a measurement of internal corporate performance whereby a company's management team evaluates the return generated relative to the company's minimum required return. Alternatively, in personal finance, residual income is the level of income that an individual has after the deduction of all personal debts and expenses have been paid.
