I think that's where the differentiator is sitting at. As an entrepreneur I used work any time that I wasn't sleeping. Maybe after 3-4 days of spending 18-20h then I'd take a morning to chill and read something, or sleep in for 2h longer. Keep going and going and going. I'm still doing that often even though there's no financial gain as an unpaid FOSS dev and it more often hurts, lol.

Bottom line, you cannot compare your own business, where you make the difference, to that where you get a wage or salary, to make your boss rich. Especially in China where wages are abysmally low compared to the US or even Germany.
