The reality is that writing is typically a lonely, private and low-paying affair. For every writer kissed by fortune there are thousands more whose longing is never rewarded. When I left a 20year career in the US 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 was fond of me and so supplied my room in a New York apartment building. It was cold and had no bathroom; I bought a used manual typewriter and felt like a genuine writer.
After a year or so of this existence, 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 for a weeks' groceries, I felt I was destined to be one of those people who die wondering, "What if？" I would keep putting my dream to the test—even though it meant living with uncertainty and fear of failure. This is the "shadow land" of hope; anyone with a dream must learn to live there.
