"وقتی یک قطار از تونل می‌گذرد و تاریک می‌شود، بلیط را دور نمی‌اندازید و از قطار نمی‌پرید. آرام می‌نشینید و به مهندس اعتماد می‌کنید."

Simplified Meaning:

Sometimes in life, things get tough and it feels like everything is going wrong, just like when a train goes through a dark tunnel. During these hard times, it's important to stay calm and keep believing that things will get better, rather than giving up. Think about a train ride: if the train goes into a dark tunnel, we don't panic and try to get off. We trust that the train driver knows where he is going and will bring us safely to the other side. Similarly, when facing challenges, we need to have faith that we will come out of the difficult situation eventually. Instead of quitting or making hasty decisions, we can try to remain patient and confident that things will improve.
