"他人の失敗から学びましょう。全ての失敗を自分でするには寿命が短すぎます。"

Simplified Meaning:

Everyone makes mistakes, and that's a natural part of life. However, you can save yourself a lot of trouble by watching and learning from what others do wrong. Think about when you first learned to ride a bike. If you watch a friend fall because they didn’t steer straight, you know to be more careful with your own steering. This way, you don't have to fall yourself to understand what not to do. Life is full of different situations, and it's impossible to make every mistake yourself to learn each lesson. Therefore, observing others and understanding their errors can help you avoid making the same ones. For example, if a coworker loses their job because they were always late, you'll understand the importance of being punctual and hopefully avoid losing your own job for the same reason. By learning from others, you can make smarter choices and have an easier path.
