it's complicated; the problem is partly the life of a musician - it's not like a novelist or esayist; stay home for 6 months or a year or two and produce that book, promo it a bit, and then start again. Intellectually jazz eats itself up; the ideas are put in and out and used, and then re-used. Open forms of improv have become a problem as well, I think - if you are a "free player" and you want to work all the time, it's easiest to just get a bunch of guys together and blow - but the energy gets used up, at least for me. If you are a tune player, well, it's been done over and over and over and over and over and over and over and over.................................
I believe in a kind of free-form structuralism. Short pieces, short solos. Almost like mini-novels, though not in a representational sense. Make your point and get out. If I had a literary model I would say: the scenes of Buchner; Bruno Schulz; Brechtian episodes; Flannery OConnor; the early novels of Handke.
Ironically, I haven't worked for 15 years; and it has actually been good for my music, bad for my mind.
