Dropping out means stopping to go to school even though you're supposed to. When you're supposed to be in school, you're learning new things and getting ready to be an adult. But if you drop out of school, you stop learning and growing. This can cause you to have fewer opportunities in the future.
It's like if you were playing a game with your friends and decided to quit halfway through. Your friends are still playing and learning new rules, but you're not. You miss out on the fun and the chance to get better at the game.
Sometimes people drop out of school because they're having a hard time with the work, don't feel like they fit in, or have other things going on in their life that make it hard for them to show up to school every day. However, dropping out can make it even harder to achieve success in the future, like getting a good job or going to college.
It's important to talk to someone if you're thinking about dropping out. They can help you find ways to stay in school and get the help you need to succeed.
