“Granted that I have the great wisdom to rid myself of the haunting dread of my own death, there remains the death of others and the death of so many feelings and so much sweetness. It is not the conception of truth that will change sorrow. Sorrow, like joy, is absolute.
And yet! The infinite grandeur of our misery becomes confused with glory and almost with happiness, with cold haughty happiness. Was it out of pride or joy that I began to smile when the first white streaks of dawn turned my lamp pale and I saw I was alone in the universe?”

After the announcement of the death sentence.

Variant: You see, I tired of constant fear, so I made a decision. Every day when I wake I tell myself that it will be my last. If you are not trying to hold on to time, you are not so afraid of losing it.
