简答题:请将下列材料翻译成中文：
It is easy to underestimate English writer James Herriot. He had such a pleasant, readable style that one might think that anyone could imitate it. How many times have I heard people say, "I could write a book. I just haven't the time. " Easily said. Not so easily done. James Herriot, contrary to popular opinion, did not find it easy in his early days of, as he put it, "having a go at the writing game".
While he obviously had an abundance of natural talent, the final, polished work that he gave to the world was the result of years of practising, re-writing and reading. Like the majority of authors, he had to suffer many disappointments and rejections along the way, but these made him all the more determined to succeed. Everything he achieved in life was earned the hard way and his success in the literary field was no exception.
