This is a tough topic to cover, but something I'd totally expect you to take on.
I personally loved the idea of Story Grid and there was a huge amount that I ultimately took from it.
I don't think I'd ever be able to take on the full grid but I really liked the Foolscap breakdown.
I actually haven't tried the Snowflake Method yet, but it was really popular in the writing circles I was part of on Instagram a few years back.
I should try the exercise and see how it plays out.
Story structure really is one of those things I think any serious writer should take on to understand. Whether freewriting or planning, it's critical to be done at some point.
It makes sure that your story is complete, that it has resonance, that it connects, and builds. I can only hope this message reaches lots of writers out there and encourages them to give this a go!
