On one end you have guys like Paul Graham and Peter Thiel that truly believe in the startup way of life.
On the other end, you have people that quit their job at Google, posted a "Why I left Google to do a startup" article on medium, and then ended up regretting the decision years later.
Most people that start companies are either people that are unemployable and can't help themselves, or employable people that could do well in more traditional career paths. If you're in the employable group, I think it's important not to start a company for the sake of doing it because it's cool. The type of startup becomes really important. As an old man, would you regret not trying to solve this particular problem that you're passionate about? It's different for serial entrepreneurs / hustlers, who are always scheming for new ways of making money no matter what.
