" Art is a substitute for acting or living. If life is the wilful expression of
emotion, art is the intellectual expression of that same emotion.
Whatever we don’t have, don’t attempt or don’t achieve can be possessed
through dreams, and these are what we use to make art. At other times
our emotion is so strong that, although reduced to action, this action
doesn’t completely satisfy it; the leftover emotion, unexpressed in life, is
used to produce the work of art. There are thus two types of artist: the
one who expresses what he doesn’t have, and the one who expresses the
surplus of what he did have. "

― Fernando Pessoa , The Book of Disquiet
