Life happens too fast for you ever to think about it. If you could just persuade people of this, but they insist on amassing information. – Kurt Vonnegut, Jr.

Never forget that you must die; that death will come sooner than you expect… God has written the letters of death upon your hands. In the inside of your hands you will see the letters M.M. It means “Memento Mori” — remember you must die. – J. Furniss, Tracts for Spiritual Reading

As if you could kill time without injuring eternity. – Henry David Thoreau, “Economy,” Walden, 1854
