To think that the affairs of this life always remain in the same state is a vain presumption; indeed they all seem to be perpetually changing and moving in a circular course. Spring is followed by summer, summer by autumn, and autumn by winter, which is again followed by spring, and so time continues its everlasting round. But the life of man is ever racing to its end, swifter than time itself, without hope of renewal, unless in the next that is limitless and infinite.
Miguel de CervantesIt seldom happens that any felicity comes so pure as not to be tempered and allayed by some mixture of sorrow.
Miguel de CervantesIt's up to brave hearts, sir, to be patient when things are going badly, as well as being happy when they're going well ...
