One of these 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.
Yesterday is gone.
Tomorrow is also beyond our immediate control. Tomorrow's sun will rise, either in splendor or behind a mask of clouds - but it will rise. Until it does, we have no stake in Tomorrow, for it is yet unborn. This leaves only one day - Today. It is not the experience of Today that drives men mad - it is the remorse or bitterness for something which happened Yesterday and the dread of what Tomorrow may bring.
