Samuel Beckett said this quote

But even them, my pains, I understand ill. That must come from my not being all pain and nothing else. There's the rub. Then they recede, or I, till they fill me with amaze and wonder, seen from a better planet. Not often, but I ask no more. Catch-cony life! To be nothing but pain, how that would simplify matters! Omnidolent! Impious dream.
