I know, because I've been there, myself. It's been 22 years since I first set out in this business. You know how it ended for me ten years ago? Producing a weekly 15-minute segment on a 6,000-watt FM in a county of 40,000 people, getting paid nothing. You know what I do now? Public address announcing for high school and college sports, mobile DJ'ing, web design, graphic design, motion graphics and video production with the occasional radio production on the side. I'm making more money now than I ever made in radio, and I have more potential to increase that income than anyone just starting out in radio today will ever have. That was the case even ten years ago.
By all means, if you can get by living the dream, go for it. But don't expect it to last very long, because I can guarantee you 100% that it will not. At some point, you're going to look at your situation and say "there has to be a better way to survive than this." And I promise you, it's going to be far less than 30 years' time before you get to that point.
