From Essayful at Twitter:
1. Write in longhand: when you scratch out a word, it still exists there on the page. On the computer, when you delete a word it disappears forever. This is important because usually your first instinct is the right one.
2. Minimum number of words to write every day: no “quota.” Sometimes it will be no words. Sometimes it will be 1500.
3. Use any anxiety you have about your writing — or your life — as fuel. Ambition and anxiety: that’s the writer’s life.
4. Never say ‘sci-fi.’ You’ll enrage purists. Call it SF.
5. Don’t dumb down: always write for your top five per cent of readers.
