I remember, from a million years ago, attending a guest lecture by some photographer who put on a slide show of all the work he'd burned. In fact, he'd burned it all at once, in an attempt to be rid of it. The reaction of the crowd was somewhere between traumatized and offended, but these were mostly students and still of that (precious) mindset that all art is precious.
I used to love burning the garbage as a kid.
Mend or end; sometimes you can do both. Or at least see the end and plan for it. I've got roughly five months to deal with everything in my studio, not least of which is all this artwork, so I've started painting over some of the smaller pieces, in order to give them one last go. Again, people's reaction to this is usually bad but I don't see it as anything lost or defeated. Rather, only as things that had their day and, for whatever reason, did not work, or were not wanted (if you conceive of the art 'economy' as being based more on the wages of happiness/meaning, then you could classify these kind of works as returns).
At any rate I don't have access to a fire pit or a burning barrel.
