No one dies before his time. The time you leave behind was no more yours than that which passed before your birth...wherever your life ends, it is all there. The advantage of living is not measured by length, but by use; some men have lived long, and lived little; attend to it while you are in it. It lies in your will, not in the number of years, for you to have lived enough.
(from "That to philosophize is to learn to die", Book I, Essay 20)
