Thesis writing frustrations

I'm sitting here days on end and writing my thesis. It's hard work. It's boring. I'm bad at it. Argghh! Why can't I finish sooner! I wish I was really good at writing, words just flowing from my fingertips into the computer and on to the screen. I wish I were better at formalizing all those crazy ideas I've had and which I now have to write up to earn my Ph.D. Well, in a better world perhaps.
