Of course writing is hard work, in the general, like pretty much anything that you try to do daily come rain come shine come weal or woe is. It's running across an in the particular that's interesting, in that it tends to be a little Aha! moment that may illuminate the process for you. It may not, of course.
I've found one of my little stumbling stones. I hate writing glue. Glue, in my idiolect, is what you write to connect scenes that you've already envisioned. The "how to get from A to B" material. And I hate it.
That doesn't mean that I like the "And with one bound, Tom was free" approach either. I can deal with the "Some years after that appalling night, Phoebe received a letter" approach if it's plainly obvious that nothing material happened in the interim period, but I'm talking about the "OK, I've done the bit where he first realises things are turning a little peculiar... then there's the dénouement, I've got that pretty well settled... then there's the ending-that-isn't-quite..." and then needing something to provide the dotdotdottinesses inbetween the scenes, where they're not particularly far apart in time or space, but can't be left jammed up against each other.
So what does this tell me? Either I have to find a way of handling this kind of 'filler' writing without my revulsion getting in the way, or I have to avoid the do a synopsis - imagine key scenes - glue together method that I've been using.
