“All sales are final.”

"The moral of the story is clear: When you live with death, as part of the very way in which you approach life, you take your life more seriously. The embrace of death invigorates life. You invest each moment with seriousness. You ask real questions about why you should live in this way as opposed to that way. Each moment matters. After all, you realize that you aren’t going to get a mulligan or a do-over at any point. When you make choices in life, it’s like the sign in the store window: “All sales are final.”"
