Now I have to motivate myself much more than I had previously.
The mass-market paperback, for one, is too expensive.
I want a platform that, like a book or a magazine, I can carry into the bath or leave at the beach.
Working within the limitations of the shared world generally made the writing easier, because I didn't have to invent any of the characters or background, which is usually the hardest part.
Being a writer was never a choice, it was an irresistible compulsion.
Even if you only want to write science fiction, you should also read mysteries, poetry, mainstream literature, history, biography, philosophy, and science.
