"冒険のない人生は満足のいかないものである可能性が高いが、冒険がどのような形をとっても許される人生は間違いなく短いものになるでしょう。"

Simplified Meaning:

Living without trying new things and taking risks can feel boring and unfulfilling. Imagine someone who spends every day doing the same routine—wake up, go to work, come home, and sleep. Over time, they might feel like something is missing because everything is too predictable. But, if someone lives recklessly, taking on any adventure that comes their way without thinking it through—like jumping off cliffs without checking the water below or racing cars on busy streets—they could get hurt or worse. This balance tells us to seek excitement and new experiences but to also be smart and careful about how we pursue those adventures. For instance, someone who loves mountain climbing should prepare properly with the right gear and training, rather than just climbing any mountain without planning. By blending caution with curiosity, a person can have a fulfilling life filled with adventures that are both exciting and safe.
