Don't be discouraged by a failure. It can be a positive experience. Failure is, in a sense, the highway to success, inasmuch as every discovery of what is false leads us to seek earnestly after what is true, and every fresh experience points out some form of error which we shall afterwards carefully avoid.
John KeatsFaded the flower and all its budded charms,Faded the sight of beauty from my eyes,Faded the shape of beauty from my arms,Faded the voice, warmth, whiteness, paradise!Vanishd unseasonably
John Keats
