I tend to write in spurts. I'll spend long periods of time doing absolutely nothing, but if I hit a rhythm I can have tremendous bursts of productivity. However, right now I'm working on an article that I really like, and I'm having a lot of trouble getting words on the page. The problem is that whenever I have one of those flashes of inspiration, I get really excited and can't focus on actually writing it. Instead, I just pace around the house talking myself through it, and I don't actually write anything down. By the time I've calmed down enough to sit back in front of the computer, the moment is gone, and I still can't write.
Does this (or something similar) happen to anyone else?
