Ray Bradbury said this quote
“ I've always figured it that you die each day and each day is a box, you see, all numbered and neat; but never go back and lift the lids, because you've died a couple of thousand times in your life, and that's a lot of corpses, each dead a different way, each with a worse expression. Each of those days is a different you, somebody you don't know or understand or want to understand. ”
