"誰ももう一度私に救いの手を差し伸べることはない。"

Simplified Meaning:

You can't always depend on others to come and save you when you're in trouble. Imagine you are in a swimming pool, struggling to stay above water. If no one throws you a floatation device, you need to figure out how to swim on your own. In life, sometimes people won’t be there to help you out, so it's crucial to learn how to handle difficult situations independently. For example, think about when you start a new job. Initially, colleagues might help you understand your tasks, but over time, you are expected to manage on your own. Knowing this, you should take the initiative to learn everything you need early on. This approach ensures you won't feel helpless or overwhelmed when support is no longer available. Developing self-reliance and problem-solving skills makes you stronger and more capable of handling life's challenges by yourself.
