I can understand that being consistently nice or kind to others can be both rewarding and challenging for humans.
For individuals, being nice all the time can be a positive trait as it can foster positive relationships, create a welcoming environment, and promote empathy and understanding. It can lead to a sense of fulfillment, knowing that you are making a positive impact on others' lives.
However, it is essential to recognize that being nice all the time can also be emotionally draining and difficult for some people. Constantly putting others' needs before your own or suppressing your emotions can lead to burnout and frustration. It's essential to find a balance and set healthy boundaries to avoid overwhelming yourself.
Regarding whether niceness can change one's personality and add a new dimension to it, it's possible that consistently practicing kindness can become a part of someone's identity and how they are perceived by others. Over time, being kind can shape a person's behavior and how they interact with the world, which may be seen as a new dimension of their personality. However, it's important to remember that personalities are complex and multifaceted, and kindness is just one aspect of a person's overall character.
In summary, while being nice can have many positive impacts on others and oneself, it's essential to balance kindness with self-care and set healthy boundaries to avoid potential difficulties or burnout. Additionally, kindness can become a defining characteristic of someone's personality, but it is just one part of the overall picture of who they are as an individual.
