I lurk here quite a lot reading various peoples experiences, with a general sense that I am not getting enough done! I was dying to comment on the thread about how many hours people put in, but when I worked it out it just made me worry more. I do a lot of teaching, and this takes up more time that should (I do love teaching though).
Anyway, I had my first panel review meeting yesterday, and all three were very impressed with the progress I'm making and very positive about the direction of my research! So I must be doing something right after all.
Just thought I'd share that with everyone. I guess I'm trying to make the point that a few (sometimes very few) focused hours work just as well as a lot of unfocused ones.
