Just to give you an idea how these systems work in an UNSCRIPTED life, here is a complete list of the legacy systems currently working for me: Digital Product Systems: eBooks, MP3 audiobooks (product sales) Software Systems: forum (advertising/sponsor revenue, monthly membership revenue) Product Systems: physical books, audiobooks (product sales) Rental Systems: foreign-rights licenses (royalties on international translations) Rental Systems: rental real estate (monthly rent) Money Systems: interest, dividends (monthly/quarterly payments)
