"私は、すべての権利には責任が伴い、すべての機会には義務があり、すべての所有物には義務があると信じています"

Simplified Meaning:

When you have certain rights, you also have things you need to do to support those rights. For example, if you have the right to free speech, you should also use that speech responsibly, not to harm others. When you are given a chance to do something good or exciting, it's important you take that chance seriously and act in a way that fulfills any promises or expectations. Imagine you get a job offer; with that opportunity, you have the obligation to work hard and do your best. Finally, when you own something valuable, like a car or a home, it's your job to take care of it properly. This quote is about balancing what we are given or entitled to with what we should do in return. So in everyday life, always think about how you can act responsibly with the rights, opportunities, and possessions you have.
