Rohn was a successful entrepreneur and motivational speaker who, after having founded several successful direct marketing companies, went on to hold speeches and mentor other like-minded people in business. Most famously, he trained Herbalife International founder Mark R. Hughes—and the rest of that MLM success story is history. The rest of the quote goes, “(…) But it won’t be long before I’m working full-time on my fortune. Can you imagine what my life will look like?” The takeaway here is that careers are slow to build, require massive time investments, and, in the long run don’t mean you’ll have too much to retire on—if you only rely on them. So, then, what are some sound ways of building residual income these days?

The reason I consider dividends artificial and believe they don’t matter is because you can just as easily reinvest your dividends. If a stock is worth $100/share, I don’t care if it issues a $1/share dividend or if the share price instead increases to $101/share – either way, I have the same amount of money, because there’s no difference to my net worth whether I take the dividend or sell part of a stock.

Residual income is calculated as net income less a charge for the cost of capital. The charge is known as the equity charge and is calculated as the value of equity capital multiplied by the cost of equity or the required rate of return on equity. Given the opportunity cost of equity, a company can have positive net income but negative residual income.
