One thing I’ve learned working for myself and building passive income is that you absolutely must have different income sources. Any one of these residual income strategies can make you a lot of money but to really find financial independence, you can’t depend on just one stream of income. Diversify your income by putting together a strategy of multiple streams of income and you’ll never have to worry about money again!

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.
