That's no doubt true in general, but culture can also have a very strong influence, either suppressing or encouraging such feelings.
Japan's "ganbatte" culture, for instance, actually glorifies precisely the opposite: people are praised and admired for working hard and sticking with something despite hardships. Other east-asian cultures also have roughly similar tendencies, although the details vary a lot.
All cultures have elements of both, but I think America is relatively far towards one end of the spectrum, and while that probably has good effects in encouraging risk-taking and invention, it also has bad effects in making people intolerant of the sort of hard work that's usually also necessary to really accomplish something.
