"たいていの場合、物の価値について教えてくれるのは失うことです。"

Simplified Meaning:

People often don't realize how important something is until it is gone. Imagine you have a favorite toy that you love to play with every day. One day, you lose that toy. Suddenly, you notice how much you miss it and how much you enjoyed having it. This makes you understand how special it was to you. In life, this idea can apply to more than just toys. Sometimes we take things for granted, like our health, friends, or family. When we get sick or lose someone we care about, we suddenly see how valuable they were. This feeling can teach us to appreciate and take better care of the things and people that matter to us before they are gone. By recognizing the value of what we have now, we can live a more grateful and mindful life, cherishing every moment and relationship. This way, we don't have to wait for a loss to understand their importance.
