Passive income. The 4 hour work week. The dream. As a millennial there are few things that rank as desirable as finding a recurring source of income that doesnt take much work (or a boss). In April of 2015 I decided to seek that out and build a side project that could pay my bills while I read books and traveled the world. Within a few months I achieved my dream and booked $5,000 in monthly recurring revenue (MRR).
