I've never attended any such workshops.
They claim they'll teach you "techniques".
You get the "tools": A story should have a begining, a middle and an end.
Draw a map. Make a list of your characters. Use simple language. Make sure you're understood.
Stiffle your inner voice. Don't let it go wild. You're here to entertain. Just tell your story and let the editor clip the seams.
Teaching techniques is "murder to dissect" for me.
In my experience, as you plunge deeper, you do better on your own. I would say even that you have no choice but stay on your own and dive, or stay on the surface and play with friends, splashing water. Beware of writing workshops, stay away from journalism - so you won't get conditioned to think what does the reader expect, instead of paying respect to what you yourself are expecting from your writing - to stay true to your singular voice.
Don't support the book "trade", not as a reader and for sure not as a writer. This troll insults your intelligence, pollutes, endangers our culture and literary heritage.
