The graphic says it all: one free chapter at the top, book sales dripping out the bottom. Instead of you tweeting your lungs out, an automated funnel quietly does the pushing. Your job is to write something worth reading once, then let systems keep introducing new readers every day.
In the image, a single "Free book chapter" box feeds into email icons, then into more book offers. That is your new job description. Give away a killer sample, collect emails, follow up with short, helpful messages, and occasionally ask for the sale. The automation arrows on the graphic mean this runs while you sleep, travel, or write the next book.
