"覚えていてください、助けが必要になったときは、あなたの腕の先にそれを見つけるでしょう。成長するにつれて、自分自身を助けるための手と、他の人を助けるための手の二つがあることを発見するでしょう。"

Simplified Meaning:

Everyone has to learn to take care of themselves first before they can help others. Think about a time when you had to figure out how to do something tough on your own, like fixing a bike or cooking your first meal. You realized that you could rely on yourself to get things done. As you get older, you understand that your left hand, for example, can be used to help you accomplish your tasks and take care of yourself. However, life isn't just about looking after yourself; it's also about supporting others. Imagine you've become good at fixing bikes. Now, when a friend’s bike breaks, you can use your skills—your other hand—to help them. So, one hand, your experience and abilities, is for your own problems, and the other is for lending a hand to people around you who need support. This balancing of self-care and assisting others can lead to a more fulfilling and connected life.
