All Those Fancy Templates

I’m sure everyone knows about the templates available for Scrivener on the Web: Snowflake Method, 40 Chapter Method, Hero’s Journey, Save the Cat, etc., etc. Would you recommend any of these as having great value?

Only if you find the “method” of any great value. Try them and see if anything resonates with you. I think you will find many similarities between them. Pick and choose what works for you and discard the rest. The best voice is the one that works with you and what you are trying to write.
