One thing we can learn is the importance of true friendship. The three idiots in the story support each other through thick and thin. Also, it shows that the traditional education system might not be suitable for everyone. Some students are creative and have different ways of learning, and we should respect that. The characters in the story break free from the rigid academic norms and find success in their own ways, which is an inspiring lesson for all of us.
We can learn to follow our passion. In the story, the main characters don't just blindly follow the traditional path but pursue what they love.
