Skriv om det du känner till

As for “Write what you know,” I was regularly told this as a beginner. I think it’s a very good rule and have always obeyed it. I write about imaginary countries, alien societies on other planets, dragons, wizards, the Napa Valley in 22002. I know these things. I know them better than anybody else possibly could, so it’s my duty to testify about them.

/Ursula K. Le Guin
