Making your own internet income. It's important.

"If you don't have (your own source of) income... you're living a very risky life.  There's no security in a job, even a high-paying one.  Be smart and don't rely on just one source of income."   

-Ray Higdon

"If you don't find a way to make money while you sleep, you will work until you die."    -Warren Buffett
