　　 1. The world is like a mirror: Frown at it and it frowns at you; smile, and it smiles too.

　　The world is a reflection of ourselves, and it shows us how we treat it. If we frown at the world, it will frown back at us. However, if we smile at it, it will smile back at us. This is a powerful reminder of the importance of our interactions with the world and how they can either harm or help us.

　　This saying can be applied to many aspects of our lives. For instance, when we are faced with adversity, it is natural to frown and become upset. However, by smiling and being kind to others, we can create a more positive environment and spread more positivity.

　　Similarly, when we are faced with success, it is natural to smile and celebrate. However, it is important to remember that our success is not dependent on others and that we should not take it for granted. By maintaining a positive attitude and helping others, we can continue to grow and succeed.

　　In conclusion, the world is like a mirror, and how we treat it reflects back at us. By smiling and being kind to others, we can create a more positive environment and spread more positivity in our lives.
