You could leave life right now. Let that determine what you do and say and think. - Marcus Aurelius

If man reflects on the changes and transformations which follow one another like wave after wave and their rapidity, he will despise everything which is perishable.

"Leaves, some the wind scatters on the ground—So is the race of man." Leaves, also, are thy children; and leaves, too, are they who cry out so if they are worthy of credit, or bestow their praise, or on the contrary curse, or secretly blame and sneer; and leaves, in like manner, are those who shall receive and transmit a man's fame to after-times. For all such things as these "are produced in the season of spring," as the poet says; then the wind casts them down; then the forest produces other leaves in their places. But a brief existence is common to all things, and yet thou avoidest and pursuest all things as if they would be eternal.

What stands in the way becomes the way.
