“Inspiration” is essentially a headspace that is connected to mental health first thing, if you conceptualize it in a way that sounds legit. As someone who published both research works (and could do that even in the worst times of my life because it’s simply work) and fiction, that I did struggle to retrieve at times, because going to the headspace of imaginary worlds and events when people close to you suffer is challenging and there is a block, I can tell you that it absolutely is not “rubbish” and you have no authority to speak on it whatsoever. The greatest minds of civilizations couldn’t finish their works, destroyed it, destroyed themselves over it, but sure, it’s rubbish lmao
