“Life is a peculiar commodity, with dimensions of its own. Still, if you were to live a million years, engaged in continual pleasures of mind, spirit and body, so that every day you discovered a new delight, or solved an antique puzzle, or overcame a challenge; even a single hour wasted in torpor, somnolence or passivity would be as reprehensible as if the fault were committed by an ordinary person, with scanty years to his life.”
