goss -- It's not so much that I want to throw things out, but periodically circumstances (such as moving, running out of space etc) force me to, so I have purges.

lim -- I throw everything out that I don't need anymore once I'm finished with a piece of art. Decluttering is my lifestyle choice.

shadowvalkyrie -- I keep some preliminary work, but only if the study/sketch/doodle/whatever looks nice in its own right, might be still of use for something later, is in a sketchbook which I keep intact, or I have some other reason for keeping it. The rest I throw out.

astridv -- I keep some preliminary work, but only if the study/sketch/doodle/whatever looks nice in its own right, might be still of use for something later, is in a sketchbook which I keep intact, or I have some other reason for keeping it. The rest I throw out.

gnatkip -- I work fully digital, so I don't produce these kinds of paper piles in the first place (and digital storage is cheap and plenty these days).

thirdblindmouse -- Your radio buttons oppress me with their limited choices. I will explain further in a comment.

maire -- I keep everything, I might become/already am famous and my complete work process is worth preserving for posterity. Future scholars will love my estate. (If they ever manage to find anything in the boxes full of junk.)

iamza -- It's not so much that I want to throw things out, but periodically circumstances (such as moving, running out of space etc) force me to, so I have purges.
