I"ve had the same problem, and have also recognized that its really a mindset / perception problem - the bookshelf I have at home is really no different than the one at the store. I could never, ever read them all, so I likewise shouldn't stress about my "read later" list. Its just a repository of interesting "when I have time for it" items. Thinking like that is not a hard-switch thats easily flipped, but by consciously recognizing and directing my thought patterns, its helped. One random thing that has also helped is (inspired by another post) I organized my books by color. Silly little idea. But now that they are both "to learn" and "decoration", i feel less guilty about the ones I haven't read yet.
