Someone once told me that no matter what skills, it is only good for you to learn one more. What do you mean?

I'm glad to answer your question. As the saying goes, many skills are not overwhelming. That's what it means. As long as you have a skill, it is always a means of making a living. Of course, there are only advantages and no disadvantages. I wish you a happy life. I hope my answer can help you. Your adoption is the greatest encouragement to me.
