"私たちは歳を重ねるにつれて幻想を失いますが経験と理解を得ます。"

Simplified Meaning:

When we're young, we often have dreams and ideas about life that aren't always true or realistic. For example, a child might think they can be a superhero and fly, or everything in life will be easy and fair. As we get older, we start to see things more clearly. We realize superheroes can't actually fly and life has challenges. With these realizations, we become more experienced and understand how the world really works. This experience helps us make better decisions and handle problems more effectively. Instead of seeing life through rose-colored glasses, we learn to see things as they are. For instance, someone who dreams of becoming a famous singer may face rejection and criticism, but through these experiences, they learn the reality of hard work and perseverance. They might not achieve fame, but they'll gain valuable skills and insights that help them in other parts of their life. This trade-off between losing some of our youthful fantasies and gaining practical wisdom and experience is a natural part of growing up.
