With Guilds I put this down to writing in strict meter, (almost) insisting on perfect scansion, and not settling for anything less than perfect rhymes. Absent any storytelling or audience experience, this is a tremendous technical challenge which a number of songwriters whom I respect don't even attempt (I have a blog post in mind about this, so no more detail here). Writing songs in this manner is, by necessity, very slow, and requires the laborious making of a lot of lists of e.g. appropriate rhymes (even Sondheim hates this bit). I resolved that my next project would not tie me (kangaroo) down in this manner.
So to Upbeat. I have just had a weekend largely free of distractions, a sizeable portion of which I spent writing. Total output: about 2,200 words. Is there any wonder this novel is nowhere near completion over 2 years since I started? If easy writing is like vomiting, then this is akin to giving birth to bricks. It's good stuff. I like what I'm writing, and it is increasingly full of nuance and subtle character interactions. Yet I find it so hard to write - my mind wanders off into distant parts of the narrative, worrying how each sentence will fit in to the whole. I question every word, every choice of syntax, every punctuation mark. I lose concentration - a lot. In short, it takes fucking ages.
Why bother? Reading yesterday's output, or especially the day before's (which has probably had a brief edit by now), is a joy - assuming that it's any good, of course.
I hate writing, but I love having written.
