This list is about some of the most popular writers who were over the age of 35 when they became famous. But I was talking to a successful writer on Reddit. They weren't super famous, but they made a good living from writing and selling some YA and fiction. They weren't overnight millionaires, but they did end up starting a small publishing company. They made a solid living, and they were able to raise a family and save for retirement. I don't think they made it to the top of any bestseller lists, but I would still call them a very successful writer.
This is also one of the reasons why I like the Indie Hackers community [1], and also the SaaS podcast [2]. I really like reading stories about people who are building SaaS products that eventually make it $100k per year in revenue. I find these stories much more interesting and relevant than reading about huge fundraising rounds, or the history of Uber and Facebook. You have a much greater chance of success with a smaller sustainable company instead of a crazy moonshot. But you won't get featured in TechCrunch, and you won't make it onto any of these 30 under 30 lists.
