One of the great advantages of being a freelance writer is having the choice to write on whatever grabs your interest. But that blessing is also a curse if your curiosity knows no bounds, as does mine. Given the demands of life and the need to make a living, the curious writer can devote only so much time to explore the vast universe of subjects suitable for his craft. Not all of us can be like Isaac Asimov, the master of science fiction who wrote over 500 books in his lifetime on every topic imaginable, not including short stories, essays, and criticism.
So every writer must answer these questions: What do I want to write about? More importantly, why do I write?
