We cannot be sure of having something to live for unless we are willing to die for it — Che Guevara. Argentine revolutionary (1928–1967)
Let the world change you and you can change the world. (Deje el mundo cambiarle y usted puede cambiar el mundo.)
Whenever death may surprise us, let it be welcome if our battle cry has reached even one receptive ear and another hand reaches out to take up our arms.
