I agree with this. I know I am in air. And I know my culture is different from other cultures. I may not completely grasp the significance but I don't need to because I'm not switching cultures any time soon. If I were to decide to emigrate to Singapore, then I'd go ahead and learn about their culture. What value is it to me to know that people in Singapore don't see entrepeneurism the same way that I do? Maybe of my local peers don't see it the same way I do either. We are all different. Regardless of culture.

I think that the fish-water analogy is pretty weak, and the entire culture ignorance concept is irrelevant for most individuals.
