One of the hardest bits about writing a book is when you get an idea that demands a significant rewrite - the sheer amount of work that can entail - as well as the casting an cutting off hours and hours of former labour - is genuinely emotionally exhausting. Often I have to take a bit of time

out to build up my energy levels to tackle the task. Wonder if anyone else feels like this? Seems like one of those things that's not necessarily discussed that much - the sort of emotional marathon that comes with draft after draft. And then there's the endless question: is it any good?
