One of the two days is Yesterday, with its mistakes and cares, its faults and blunders, its aches and pains. Yesterday has passed forever beyond our control. All the money in the world cannot bring back yesterday. We cannot undo a single act we performed. We cannot erase a single word we said.
Yesterday is gone.
Tomorrow is also beyond our immediate control. Until it does, we have no stake in tomorrow, for it is yet unborn. Let us, therefore, live but one day at a time.
