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 adversaries, it's burdens, its large promise and poor performance.

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 as yet unborn.

This leaves only one day - today. Any one can fight the battle of just one day. It is only when you and I add the burdens of these two awful eternities - yesterday and tomorrow - that we break down.

It is not the experience of today that drives us mad - it is the remorse of bitterness for something which happened yesterday and the dread of what tomorrow may bring.
