a. Write a 250-word essay on "Independence vs. Interdependence" 
 Independence vs. Interdependence

The concept of independence has always been glorified in our society. We have been taught that being independent is a mark of strength and success. We are often told to stand on our own feet, take charge of our lives and not rely on others. However, this mindset of absolute independence has caused us to overlook the value of interdependence.

Interdependence is the idea of relying on each other, supporting one another and working together to achieve a common goal. It is the backbone of any functioning society. No one can achieve everything on their own, and when we rely on each other, we create a sense of community and belonging.

The over-emphasis on independence has created a culture of competition and self-centeredness. We are encouraged to pursue our own goals and dreams, without considering the impact it may have on others. This has resulted in a society where people are increasingly disconnected from one another, leading to loneliness and alienation.

On the other hand, interdependence fosters a sense of connection and belonging. When we work together, we create a stronger society, and everyone benefits. It also teaches us the value of empathy, communication and compromise, essential skills for any functioning relationship.

In conclusion, while independence is necessary for self-reliance, it is essential to recognize the value of interdependence. It is not an either-or situation, but rather a balance between the two that creates a harmonious and healthy society. We need to understand that our actions have consequences and consider how they may affect others. The world is becoming more interconnected every day, and it is vital that we learn to work together to achieve a common goal.

B. Write a newspaper article highlighting the increasing individualism in the modern Nepali society.

Nepal is a country with a rich cultural heritage and strong community ties. However, the modern society is increasingly becoming individualistic, with people prioritizing their personal goals and aspirations over community welfare.

The education system in Nepal is one of the factors that contribute to this trend. The system is geared towards producing individuals who can succeed in a competitive environment, often leading to a culture of self-centeredness. Students are encouraged to focus on their grades and personal achievements, often neglecting the importance of social and emotional learning.

The influence of Western culture has also played a role in the rise of individualism. The advent of social media has made it easier for people to connect with others globally, but it has also created a culture of self-promotion and comparison. People are now more concerned with their own image and personal brand, rather than their contribution to society.

The increase in urbanization and migration has also led to a breakdown of community ties. People are moving away from their ancestral homes to urban centers, where they are more concerned with their personal goals and aspirations than community welfare.

In conclusion, while individualism has its benefits, it is essential to recognize the importance of community and social welfare. Nepali society has always been based on a sense of community and collective responsibility. We need to create a balance between personal growth and community welfare, and ensure that we are not sacrificing one for the other. By working together, we can create a more harmonious and compassionate society.
