I think "recurring revenue" is a bit misleading in the title, the author seems to be talking about passive income. Income that keeps rolling in even when you cut back the hours you put into it. Once you've written a book or a piece of software and put it for sale, you can start working on your next product which hopefully opens up another stream of income. You don't need to sell $650/day of one product. You can also sell $65/day of 10 products each.
