As an entrepreneur/solopreneur who sold several businesses there among an live entertainment division, esports club and a record label, then I concur that way too many people have a romantized idea of what it means to be an entrepreneur, and that it's not all sex and rock and roll, living the high life, and people easily get discouraged by the amount of hard work you have to put in, lonely hours, social isolation etc.
But it seems like no matter how many articles, books, etc written about this very topic, some people just have to learn the hard away.
