"Practice makes perfect, keep cutting, and your hands are accurate!" Combine your life experience and talk about your understanding of this sentence.

This sentence was said by grandma in response to my criticism. According to the context, grandma is very familiar with magpies climbing trees, and it takes a long time to cut them, so her hands are very targeted, which is obtained from years of practice. As the saying goes, never leave your hand, never leave your mouth. Only through long-term practice can we become proficient.
