I think the reason some people on HN want to do their own thing is because the jobs we have suck so much and they feel that by doing their own thing they will take back control and be able to have the life they want.
I think it's somewhat delusional. Founding your own company, finding a great revenue stream, and getting adequate compensation with it is incredibly challenging and not a common route at all. If I want to make $500k+/yr, I am much better off joining a big public tech company.
