My approach in writing groups is to write whatever you like-it is a process you learn by yourself, but the process is shared in groups. I agree with Natalie Goldberg’s approach which is an artistic and mindful way of writing. Some of her advice is :
write from first thoughts, keep your hand moving
don’t cross out
just get it on paper
writing is ninety percent listening; the deeper you listen, the better you write
verbs provide the energy of the sentence
overcoming doubts – doubt is torture; don’t listen to it.
