I love this syntax. The expression presents a more 'suppressed' or 'depressed' feeling than would "even when you don't feel inspired."
Your choice carries more power in the feeling where the latter choice is simply a lack of something.
I don't know about the rest of you, but I've felt both at different times. The literal impact of feeling completely "uninspired", and simply the lack of having any inspiration at hand.
This is a great example of how slight differences in our syntax (choice of word organization and use) in our expression can have a significant difference in our impact on a scene and a reader.
Tolkien understood this, and by and large his clever use of it at many points is how he infused his "moral and religious elements" into his work.
I'm editing another short essay for an author now, and then will be starting to dapple with writing again.
Sorry for my absence here... there was just no room for 'inspiration' for awhile. And no doubt the future will see less opportunity than the past, but I'm determined to make use of what time I can progressing on things.
