I'm in the middle of what should be the last chapter of A Pony's Heart, but I think my creative fire from the last couple weeks is starting to die down.
I hate running out of steam part-way through chapters, but that always seems to be when I hit my walls. Never when I've finished a chapter and am about to start a new one. On the plus side, seeing an incomplete chapter sitting on my hard drive provides a strong incentive to get back in ASAP.
