What should you work on first when you start your day? Simon Rich, who has written scripts, short stories, novels, and sketches for Saturday Night Live, has some advice you might like:
"It sometimes depends on deadlines, but I've found that the most efficient thing is to write what you want to write."
Great! Permission to have dessert first.
Of course the only rule is to do what works for you. If at first you don't succeed, try something different.
