Another benefit of residual income is that, if the income stream is large enough, one does not need the main focus of his life to be on making enough money to survive. Having a comfortable and continuous level of residual income opens up more opportunities to travel, look into other business opportunities, and even take the time to indulge in his hobbies.
However, residual income typically has an expiration date, especially if it is being earned through a business. Effort must be continuously put into the business in order for someone to continue to receive residual income. Businesses must continue to market themselves in order to remain relevant. The best way to look at residual income in this sense is that it is a part-time job that earns full-time income.

PPS oh you thought I was done did you?!  The other parts of the book, although not truly passive income generation focused, are amazing too.  I know things like the low information diet and killing interruptions have made a huge difference to my success – and if I can try and get a little more consistency in my adherence to them, then happy freaking days!
