Thornton Wilder said this quote

“ The type of the Inevitable is death. I remember well that in my youth I believed that I was certainly exempt from its operation. First when my daughter died, next when you were wounded, I knew that I was mortal; and now I regard those years as wasted, as unproductive, in which I was not aware that my death was certain, nay, momently possible. I can now appraise at a glance those who have not yet foreseen their death. I know them for the children they are. They think that by evading its contemplation they are enhancing the savor of life. The reverse is true: only those who have grasped their non-being are capable of praising the sunlight. ”
