Beware of self-indulgence. The romance surrounding the writing profession carries several myths: that one must suffer in order to be creative; that one must be cantankerous and objectionable in order to be bright; that ego is paramount over skill; that one can rise to a level from which one can tell the reader to go to hell. These myths, if believed, can ruin you. If you believe you can make a living as a writer, you already have enough ego.
David BrinThere's no doubt that scientific training helps many authors to write better science fiction. And yet, several of the very best were English majors who could not parse a differential equation to save their lives.
