"要幸福我们就不应太在意别人。"

Simplified Meaning:

If we want to be happy, we need to focus on ourselves and not worry too much about what other people are doing or thinking. Imagine someone who constantly compares their life to their friends or people they see on social media. They might feel bad because they think their own life isn't as good. This makes them unhappy. Instead, if that person focuses on their own goals and what makes them personally satisfied, they will feel more content. For example, think about a student who always compares their grades with their classmates. They might get upset if someone else scores higher, even if they did well. But if they concentrate on doing their best and improving their own skills, they will find more joy in their achievements. In short, by not worrying so much about others, we can find more peace and satisfaction in our own lives.
