“Among the things Billy Pilgrim could not change were the past, the present, and the future.”

“Billy had a framed prayer on his office wall which expressed his method for keeping going, even though he was unenthusiastic about living. A lot of patients who saw the prayer on Billy’s wall told him that it helped them to keep going, too. It went like this: “God grant me the serenity to accept the things I cannot change, courage to change the things I can, and wisdom always to tell the difference.” Among the things Billy Pilgrim could not change were the past, the present, and the future.”

“Billy Pilgrim, there in the creekbed, thought he, Billy Pilgrim, was turning to steam painlessly.”

“It was never too late to learn something. The past is unalterable in any event. The future is the only thing we can change. Learning the lessons of the past is the only way to shape the present and the future.”

“Entre las cosas que Billy Pilgrim no podía cambiar se encontraban el pasado, el presente y el futuro.”

“How can the past and future be, when the past no longer is, and the future is not yet? As for the present, if it were always present and never moved on to become the past, it would not be time, but eternity.”
