Sometimes looking at a blank sheet of paper with a pen lying next to is is the only muse we need. I’ve been getting published on and off for around 50 years now (I love writing but am very lazy about getting my work published) and I’ve always said to people who ask how they can improve their writing that the best way is to forget the creative writing courses, books that purport to tell us how to write a successful novel, all the articles by ‘experts’ and any software packages that promise to improve grammar and style (like Grammarly, which will help you write the kind of stilted text found in technical manuals for software authored in China.
Read a lot, learn from what engages you, more people will benefit from Terry Pratchett than Thomas Pynchon, or from John Steinbeck than from John Fowles — don’t fall into the trap laid by pretentious literary critics and think if a lot of people like it, it must be crap. Writers who find a wide audience are obviously more in touch with the interests of more people. Nothing wrong with that.
If you feel you want to write intellectually complex prose full of obscure references, that is perhaps your “voice” but other approaches are equally valid.
