Read the following passage and choose the most likely answer to each of the following questions.
Many a young person tells me he wants to be a writer. I always encourage such people, but also explain that there's a big difference between"being a writer"and writing. In most cases these individuals are dreaming of wealth and fame, not the long hours alone at a typewriter. "You've got to want to write, "I say to them, "not want to be a writer".
The reality is that writing is a lonely, private and poor paying affair. For every writer kissed by fortune there are thousands more whose longing is never rewarded. When I left a 20-year career in the U. S. Coast Guard to become a freelance writer（自由撰稿人）, I had no prospects at all. What I did have was a friend who found me in my room in a New York apartment building. It didn't even matter that it was cold and had no bathroom. I immediately bought a used manual typewriter and felt like a genuine writer.
After a year or so, however, I still hadn't gotten a break and began to doubt myself. It was so hard to sell a story that barely made enough to eat. But I knew I wanted to write. I had dreamed about it for years. I wasn't going to be one of those people who die wondering. What if? I would keep putting my dream to the test even enough it meant living with uncertainty and fear of failure. This is the Shadow land of hope, and anyone with a dream must learn to live there.

【正确答案】：D
【题目解析】：
C项“整整一年都不能休息”原文说的是“一年左右”而不是“整整一年”且和“怀疑自己”没有因果关系。B项“他没有看到生活变得更好”也不是作者怀疑自己的原因，作者怀疑自己是因为卖书困难（而不是出书困难，排除A项）感觉成为作家的梦想很难实现，即D项。
