All noble enthusiasms pass through a feverish stage, and grow wiser and more serene. William Ellery Channing
The more I expect, the more unhappy I am going to be. The more I accept, the more serene I am. Michael Fox
In the end, the bedrock of existence is not made up of the family, or work, or what others say or think of you, but of moments like this when you are exalted by a transcendent power that is more serene than love. Life dispenses them parsimoniously; our feeble hearts could not stand more. Nicolas Bouvier
