This quote suggests that every country makes its decisions and sets its policies based on its own interests. It’s a reflection of the realpolitik approach, which emphasizes practicality and self-interest over moral or ideological considerations. Essentially, it’s a recognition of the fact that nations, like individuals, act primarily out of self-interest.

In the global context, this can be seen in how countries negotiate trade agreements, form alliances, or even wage wars. For example, a country might enter into a trade agreement not because it benefits the world economy, but because it benefits its own economy. Similarly, a country might form an alliance with another not because of shared values or ideologies, but because it provides a strategic advantage.

This idea can also be applied to personal development. Just as nations act in their own interests, individuals also need to consider their own interests when making decisions. This doesn’t mean being selfish or disregarding the needs of others. Rather, it’s about understanding what’s important to you, what your goals are, and making decisions that align with those interests. For instance, choosing a career path should be influenced by your own interests and goals, not just societal expectations or pressures.

However, it’s also important to note that while acting in self-interest is natural and often necessary, it should not lead to actions that harm others. Just as nations must consider the global impact of their actions, individuals must also consider the impact of their actions on others. So, in both national policy and personal development, a balance must be struck between self-interest and the greater good.
