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. This just leaves only one day, today. Any person can fight the battles of just one day. It is not the experience of today that drives people mad.
