Why can't I do it?

I've had over a day to start. All I need to do is get some figures together for my 2nd thesis chapter. I have plenty. Yet it took half of Monday and all day Tuesday before I got up, took all the gels and went to the scanner and scanned them. Took maybe 30 minutes. Why am I being hit by super procrastination?! I need to have a meeting with my supervisor on Friday and show him. Someone please hit me with a wet kipper and make me finish this off.
