Is this what's called failure?

Wiser (?) voices in my head tell me to stop making stuff-after all, who needs it? Who wants it?
I look around me and see what I deem to be lesser work flying out of studios, galleries, shops.
Is my work really that bad or is it that my opinion/taste is badly skewed?

A hound on a very long bad trail

Granted, I can't sell ten dollar bills for five bucks, but my salesmanship should be an irrelevant point. After all, shouldn't the work stand up for itself? Maybe not-for one thing, there's so much out there clamoring for one's attention. Or maybe I'm just so damn naive-to continue the analogy, that dog don't hunt…
A foolish thing to make work that's useless, yet to keep on with it. OK, admittedly, I think I'm doing good stuff. And besides, I do enjoy the act of working.

You'll know when I croak-watch for the huge bonfire.

A quandary along the road: more older, more confuser

I'm working on seven sculptural pieces right now.
All but one, they are all fairly well along in terms of completion.
But in working towards completion, I now question each one to the point of deadlock-
Does the piece have relevancy? Does it use too many "cliches"(conventional and/or personal)?
Am i repeating myself? Is this work too remote from "my" style (voiding consistency, therefore  credibility)? Shouldn't "good "work take longer to create?
Is this a spin with insecurity or a valid questioning?
Beginning the pieces, there were none of these doubts-I wouldn't have taken them so far along.
Working with them for so long, I'm now blind to seeing them objectively.
