one concrete thing I can name is "widening" your view on writing. force different styles upon yourself, different constraints. the results will keep being shit for a while, but at least it will be very fun to tonally cosplay Shakespear before the mirror! you won't notice how time will pass :)

listening to narrations of vast variety of poetry and narrating something yourself will help you develop your specific voice and read with more intent.

you may not even need the "science of writing" this article describes. let yourself just... be with text.
