Self-interest makes some people blind, and others sharp-sighted.

This quote suggests that self-interest, or the focus on one’s own personal gain or advantage, can have two contrasting effects on people. For some, it can make them “blind,” meaning it can cloud their judgment, distort their perspective, and make them oblivious to the consequences of their actions. They may become so consumed by their own desires and ambitions that they fail to see the potential harm they may cause to others, or even to themselves in the long run.

On the other hand, for others, self-interest can make them “sharp-sighted.” It can enhance their perceptiveness, their ability to recognize opportunities, and their strategic thinking. They can use their self-interest as a tool to navigate the world more effectively, to make better decisions, and to achieve their goals in a way that is also beneficial to others.

In today’s world, this idea is particularly relevant. For instance, in business, some leaders, driven by their self-interest, may resort to unethical practices, neglect their employees’ welfare, or disregard the environment, thus becoming “blind.” However, other leaders may use their self-interest to innovate, to create value for their customers and employees, and to contribute to their community, thus becoming “sharp-sighted.”

In terms of personal development, this quote serves as a reminder of the need for balance and mindfulness. While it’s natural and healthy to pursue our own interests, we should also strive to remain aware of the bigger picture and consider the impact of our actions on others. This way, we can use our self-interest as a driving force that leads us towards growth and success, without losing our sense of empathy, fairness, and responsibility.
