It is important to approach generalizations like "the world is predominantly sad" with caution. While it's true that people face various challenges and hardships, it's not accurate to say that everyone is predominantly sad all the time. Happiness and sadness are complex emotions experienced by individuals and can vary greatly based on circumstances, personality, and cultural factors.
As for the idea of trusting no one because sadness is a lie and happiness is the truth, this is a very simplistic view of human emotions and relationships. Emotions, including both happiness and sadness, are valid and real experiences for individuals. People can experience both genuine happiness and authentic sadness at different points in their lives.
Trusting others is an essential aspect of building meaningful relationships and a supportive social network. While it's true that some people may be dishonest or untrustworthy, it's not helpful to generalize this to everyone. Instead, it's essential to develop discernment and judgment in whom to trust, based on their actions and character.
Building trust involves being open, vulnerable, and honest with others while also setting healthy boundaries to protect oneself. Trusting others doesn't mean blindly believing everything they say, but it does involve giving people a chance to prove their reliability and integrity.
Human relationships are complex, and it's natural to encounter both honest and dishonest people in life. Still, it's essential to maintain a balanced perspective and not let fear of potential betrayal isolate us from forming genuine connections with others. Trust can be earned over time through mutual respect and consistent honesty in relationships.
