"نوشتن کتاب مبارزه‌ای وحشتناک و خسته‌کننده است، مثل دوره بلندی از یک بیماری دردناک. هیچ‌کس چنین کاری را انجام نمی‌داد اگر نیرویی او را مجبور نمی‌کرد که نمی‌تواند در برابرش مقاومت کند یا آن را درک کند."

Simplified Meaning:

Writing a book is often a tough and tiring process. It can feel like you're going through a hard and painful time, similar to having a long-lasting sickness. Normally, nobody would choose to do something so challenging unless they felt an uncontrollable force inside them pushing them to do it. This inner force could be a deep passion, a burning need to tell a story, or a powerful desire to share a message with the world. Take, for example, a person who decides to run a marathon. Training for such a race involves hours of practice, muscle pain, and mental stress. It's not easy, and there are many moments when the person might want to quit. However, something inside them, like a dream of achieving a big goal or the joy of personal accomplishment, keeps them going despite the difficulties. In the same way, a writer is driven by a strong inner motivation to complete their book, even though the process is very demanding. This motivation can help anyone facing a hard task by reminding them of their deeper reasons and keeping them focused on their ultimate goal.
