I feel like I don't get much done (at least not as much as I'd like), so here's a list of how I spend my non-work time during the week.
Fun: Battlestar Galactica (1 hr), Lost (1 hr)
Exercise: hockey practice (3 hrs), gym (6-8 hrs)
Class: Noise and dissipation lecture (3 hr), Theory of Solids reading group (1 hr)
Meetings: Meeting with advisor (1 hr), postdoc meeting (2 hrs), group meeting (1.5 hr), condensed matter theory seminar (1 hr), physics colloquium (1 hr)
Sleeping (56 hr)
Eating (21 hr)
News reading and email (??)
Which leaves me 67.5 hours during the week to do "real" work. My real work consists of doing reading for classes, attempting problem sets, reading the arXiv, doing research, and organizing my research/class/etc materials.
I'm going to start keeping time cards everyday to see what's going on.
