I have ot work on my lecture on 14th century fashion for Sunday and it's pouring down outside and I feel very bored. The problem with the lecture is of course that I know the subject so well that it is hard to actually start working, since in the back of my head there's a voice saying: "You don't need to do this, you can do this without preparation". But no, I can't, a good lecture demands good preparation even if you know the subject. And since the museum is paying me for it I need to do a very good job.
