"All is pretty."
"I like boring things..."
"I never read, I just look at pictures."
(Andy Warhol)
This makes me feel like reading your book again. "The Philosophy of Andy Warhol: From A to B and Back Again." Damn, I don't have it anymore. Never mind, I'll get a new copy, the English edition this time.
Don't worry if you give something away you might want again later. You can get it back, in a new or enhanced version that suits your current reality better. Or in the same version if that's still good (well, can it really be the same?). I guess that's true for everything we play with: books, things, places, people, animals, nature, circumstances, thoughts, feelings, ideas, perceptions, ...
Nothing is ever lost. It's all just transforming, dancing with each other, as life itself.
