If you have to find devices to coax yourself to stay focused on writing, perhaps you should not be writing what you're writing. And if this lack of motivation is a constant problem, perhaps writing is not your forte. I mean, what is the problem? If writing bores you, that is pretty fatal. If that is not the case, but you find that it is hard going and it just doesn't flow, well, what did you expect? It is work; art is work.
Ursula K. Le GuinThe trouble is that we have a bad habit, encouraged by pedants and sophisticates, of considering happiness as something rather stupid. Only pain is intellectual, only evil interesting. This is the treason of the artist: a refusal to admit the banality of evil and the terrible boredom of pain.
Ursula K. Le GuinFantasy is not antirational, but pararational; not realistic but surrealistic, a heightening of reality. In Freud's terminology, it employs primary not secondary process thinking. It employs archetypes which, as Jung warned us, are dangerous things. Fantasy is nearer to poetry, to mysticism, and to insanity than naturalistic fiction is. It is a wilderness, and those who go there should not feel too safe.
