Long shot

Long shot means trying to do something that is very difficult or unlikely to happen. It's like trying to hit a target that is very far away. It might be possible, but you don't have a good chance of succeeding. For example, imagine you want to become an astronaut. It's a long shot because it's very hard to become an astronaut. First, you need to study a lot and get good grades in school. Then you need to go to college and study things like engineering, physics, and math. After that, you need to apply to become an astronaut and go through a lot of tests and training. It's a long shot because only a few people get to be astronauts, and it's very hard work to get there.
