I'm 41 and just started working on my thing a couple of months ago. I'm married but we don't have kids nor a mortgage because we've been digital nomads for the most part of the last 10 years. My wife is doing well economically so we decided together it was a good time to start working on something that will not generate income in at least 2 years. After 20+ years in dev I got tired of making projects for others and finally decided on an idea that could work financially. Not to grow to millions of users, but to at least support myself.
