I am reminded of the story told by Attar of Nishapur, of a Persian king who desired a magic ring. He assembled a group of wise men to create a ring that would make him happy when he was sad. The ring they forged was inscribed with the phrase "This Too Shall Pass."
It is a maxim that serves as both a source of comfort during times of stress, but also as a cautionary tale when your successes are forthcoming.
Remember that in both your times of horniness and frigidity. This too shall pass.
