Clipping from Hacker News comment section...
Maturity is to conclude that working for other people sucks? I don't think my parents would agree with that. My dad wasn't particularly lazy on the job before he retired.
I mean... I do think working for somebody else sucks, but starting and running a successful business isn't trivial.
I suspect that this definition of maturity isn't found outside of the entepreneurial crowd that you find on Hacker News.
