Ralph Waldo Emerson, letter to Frederic Henry Hedge (March 14, 1836):
To write a very little takes a great deal of time. So that if one indulges in that species of dissipation he will have little to show for his solid days. And there are not many greater misfortunes to peace of mind than to have keen susceptibility to the beautiful in composition and just to lack that additional wit which sufﬁces to create it.
So shall a man weary himself and spend good oil in vain attempts to carve Apollos which all turn out scarecrows.
