Beauty is truth, truth beauty, --that is all Ye know on earth, and all ye need to know. — John Keats. English Romantic poet (1795–1821)
The only means of strengthening one's intelligence is to make up one's mind about nothing-- to let the mind be a thoroughfare for all thoughts.
I am certain of nothing but the holiness of the heart's affections and the truth of imagination. What the imagination seizes as beauty must be truth - whether it existed before or not.
Poetry should please by a fine excess and not by singularity. It should strike the reader as a wording of his own highest thoughts, and appear almost as a remembrance.
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.
