Instead of an income stream, develop an income river. Develop an entire watershed. Be a rainmaker. Dam up some of that money behind an emBANKment for the inevitable droughts. Use some of the money for irrigation of the orchards and fields of your own imagination.
Paychecks are like buckets of water dolled out by some corporation.
Develop your own river of income fed by the deep wellspring of your own wisdom. My life is an aurora borealis. Or a never-ending story. Or a three-ring circus. Or a multi-flavored ice cream cone.
