The Dreaded Brick Wall!

So the last couple of weeks have been rather slow for me. My thought process has completely slowed down and the amount of work I have produced is not nearly as much as I would have liked. When I am in the zone with a project, ideas flow a I am constantly thinking about my work, so actually doing work is easy. But the last two weeks I have found difficult and have not felt very creative. I think because I strive to do well and work hard, when I have times like this I am very aware that I am falling behind, which causes me to panic. And when I start to panic, I find it even harder to be creative obviously, because I am worrying about not doing enough work. I need to work on some tactics so that when I do have a slow week, I work from say a list of tasks that keeps my mind active, because lets face it, it happens to everyone sometimes. And remember next time not to worry about the amount of work because it only makes things worse.
