"他人に興味を持つようになることで２ヶ月で作れる友人の数は他人に自分に興味を持ってもらおうと２年間努力して作れる友人の数よりも多い"

Simplified Meaning:

When you show genuine interest in other people, you can build friendships much faster than if you only try to make others interested in you. For example, imagine you start a new job. If you ask your coworkers questions about their lives, listen to their stories, and show that you care about their experiences, they are likely to like you and want to spend time with you. On the other hand, if you mostly talk about yourself and try to impress them, it may take a lot longer for them to warm up to you. This advice suggests that being a good listener and showing curiosity about others is a more effective way to make friends. In your own life, you can apply this by focusing more on others in conversations, asking thoughtful questions, and really listening to the answers. This approach can help you build stronger, quicker connections with people.
