"كل ما تعتقد أنك تعرفه عني لا شيء."

Simplified Meaning:

Sometimes people think they know a lot about someone just by looking at them or hearing a little bit about their life, but often, they actually know very little about who that person really is. Imagine you see someone at school or work who is quiet and always sitting alone. You might think they are unfriendly or don't like being around people. However, the truth could be very different. Maybe this person is just shy, or maybe they are going through something tough and don't feel like talking to anyone. In real life, there are many layers to a person's story that we can't see on the surface. Just like with celebrities, fans might read about their lives in magazines or online and think they truly know them, but it's only a small part of the bigger picture. A person is made up of many experiences, thoughts, and feelings that aren't always visible. To apply this idea, try not to make quick judgments about others based on limited information. It's always good to get to know people more deeply before forming an opinion about them. Simple acts like having a conversation, listening, and showing empathy can help you understand others better.
