"What I have learned about great writers: they were always obsessed with something, but they were very seldom obsessed with writing." Jenny Boully
The cops I served burgers to asked me what good was learning anything if I couldn't help people.
I tell my students, at the end of the term, that they must have hobbies, because if they don't have hobbies, then that means writing is their hobby, and it shouldn't be that way; writing should be their life and not their hobby. I tell them to learn new things, different things, things that have nothing to do with writing. And not just learn them, but be good at them; master them; impress others with them. What I have learned about great writers: they were always obsessed with something, but they were very seldom obsessed with writing.
From the great Jenny Boully in The Poet's Education, in Betwixt and Between
She has two (two!) book coming out in 2027 and it can't come fast enough.
