This is going to sound terrible, despite not posting yesterday, but I swear this is more productive than it sounds.
After giving it A LOT of thought, I've crafted the introductory paragraph for the prologue. Main character, setting, place and time have all been established in one consise paragraph that I'm rather content with. I have to give myself a pat on the back for this one.
I can't really explain the feeling, I suppose you can call it inspiration, but I now feel I can keep putting one word after the other until the prologue is finished. Then the next chapter, and the next. I'm definitely charging ahead!
