Good girl

I was a good girl today. I worked. But I have to do a couple of things more.
I am tired. I want to sleep. I want to sleeeeeeeeeeeeeeeeep.

I have to tell me: the best dissertation is the written dissertation. I am strong. I am powerful. I can do these few more paragraphs. Everything will be fine. There is no other book on this topic, so everything I do will be fine.
I am strong. I can do this.

puh. I hope this gets me through the revision of the next paragraph.
