I've been working on this novel for a while, and I've started feeling like I need to do something else. It's not that I've run out of ideas for this novel - far from it. I've still got loads to say. It's just like I'm bored of writing it maybe, and while I'm writing there's the constant buzz of a new plot I've been thinking about for a while. This plot idea is like a mosquito while I'm trying to write - impossible to catch and kill, but really distracting. I don't know what to do. If I just "take a break" from the novel, say I'm going to go back to it later, I'm afraid it will just join the pile of great ideas that fizzled out and died.
