"Il n'y a rien de plus misérable au monde que d'arriver au paradis et de ressembler à sa photo de passeport."

Simplified Meaning:

When you get to a beautiful place, like a dream vacation spot, and you look tired, stressed, or unhappy, it's a shame because you can't fully enjoy it. Think about when you're planning a trip. You spend a lot of time and money getting ready. But if, by the time you arrive, you’re so worn out that you look terrible—like those awkward, unflattering photos on your passport—it means the journey or your worries have not allowed you to relax or feel happy. Imagine you've just flown to a tropical beach after months of hard work. You've been looking forward to this moment, but upon arrival, you’re exhausted and look frustrated. Instead of enjoying the sunny beach and the beautiful views, you might just feel too tired to appreciate them fully, missing out on the joy you’ve been anticipating. To avoid this, try to find ways to manage stress and take care of yourself during the lead-up to your trip. This way, when you finally get to your paradise, you’ll be refreshed and ready to enjoy every moment of it.
