Observe constantly that all things take place by change.
Perhaps there are none more lazy, or more truly ignorant, than your everlasting readers.
Confine yourself to the present.
Soon you will have forgotten the world, and soon the world will have forgotten you.
Past and future have no power over you. Just the present - and even that can be minimized.
Look at everything that exists, and observe that it is already in dissolution and in change, and as it were putrefaction or dispersion, or that everything is so constituted by nature as to die.
