AntiProductive

Last week or so I was doing 2000 words a day like clock work. This week I've barely written 1000. Someone told me I'm probably burned out but honestly I'm just feeling lazy. It's not that I don't feel like writing it's just I'll do a review or read or something else instead of working on my word count. I think one major thing that's deterring me from writing is how I'm writing.
In my first manuscript I plotted like a freaking wedding planner or something. I knew how every little thing was going to go down and when I turned to write it I did it too short or something and I ended up with a manuscript with 25,000. This time I started plotting but got stuck so I just started writing, then my story and the characters seem to take a whole new life I hadn't planned. People don't like not knowing and I'm almost positive that's what's keeping me from my word goal. I'm scared to know what happens next. I know exactly how I want my ending to go I'm just not sure how I'm going to get there and that makes me worried if I'll end up in the right spot.
