We are such lovers of self-reliance, that we excuse in a man many sins, if he will show us a complete satisfaction in his position, which asks no leave to be, of mine, or any man's good opinion.

There can be no excess to love, none to knowledge, none to beauty.

It does not to dwell on dreams and forget to live, but it is equally foolish to ignore the past – never forget.

The finest poetry was first experience.
