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. We cannot undo a single act we performed. We cannot erase a single word we said.
Yesterday is gone.
The other day we should not worry about is tomorrow. With its possible adversities, its burdens, its large promise and poor performance. 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.
