Oh yes, all the time! In fact, I become so daunted by the pile I create that I actually end up doing nothing! I'll start reading something, and then realise that it's not actually connected to what I'm meant to be writing about right now, so I feel guilty for wasting time when I should be reading something that will tie in to my writing, and end up abandoning it half way. I get these panic moments when I realise I haven't read anything in a while. Sometimes I'll go weeks without reading anything, because maybe I'm working on a piece of writing. We all know how much time gets eaten up with that, and your research gets put on hold when you're writing because you don't want to confuse yourself any further. I'm not one of those people who can write a bit, read a bit, write a bit, etc.
