"幸せな人は他の人をも幸せにする"

Simplified Meaning:

When you feel happy, you tend to spread that happiness to the people around you. Think about times when you've been in a good mood and how your positive energy made your friends smile or feel better. Happiness can be infectious, just like laughter. For example, if a person walks into a room with a big smile and a cheerful attitude, it can lift everyone's spirits, even if they were feeling down before. This idea shows that your emotions can affect others, so by being happy yourself, you can help make the world a bit brighter for those around you. If you want to apply this to your life, try to focus on the good things and share your joy with your friends and family; it might make their day better too.
