The dark secret is that a majority of soloists have no interest in building a major entrepreneurial enterprise. Many of them don’t even like business. These soloists thrive on the work they do, and would be very cranky if you asked them to give it up. For many, their work is a fundamental expression of their creativity.
What they want is a lifestyle. They want the holy grail of freedom and quality of life! They want to do work that feeds them, work that matters. They want to see their kids grow up. They do not want to be Donald Trump!
