Future orientation is combined with a notion and expectation of progress, and nothing is impossible.

Dundes is describing a cultural orientation in which the future is imagined as open, improvable, and governed by the expectation that conditions can get better over time. In such a worldview, “progress” is not merely possible but assumed, and that assumption feeds a rhetoric of limitless capability (“nothing is impossible”). Read this way, the line is less a personal motivational slogan than an analytic claim about how certain societies narrate time, agency, and innovation: optimism about the future becomes a cultural premise that legitimizes risk-taking, reform, and technological or social change. It also hints at a potential blind spot—confidence in progress can obscure limits, costs, or cyclical/tragic understandings of history.
