Quote from : The Museum of Innocence Book

In fact no one recognizes the happiest moment of their lives as they are living it. It may well be that, in a moment of joy, one might sincerely believe that they are living that golden instant "now," even having lived such a moment before, but whatever they say, in one part of their hearts they still believe in the certainty of a happier moment to come. Because how could anyone, and particularly anyone who is still young, carry on with the belief that everything could only get worse: If a person is happy enough to think he has reached the happiest moment of his life, he will be hopeful enough to believe his future will be just as beautiful, more so.
