So today I discovered PhinisheD.com. Finally a bunch of people having similar experiences in grad school. Today was also the start of "new me" which is actually a return to "old me". I've realized that to be happy and get work done, I actually have to work less and have more fun. So, time to make time for friends, yoga, meditation, long bike rides (thanks Jeremy for suggesting routes), and getting up early.
Let's see how long this lasts... hopefully going to Calgary for the fall will help shake things up a bit.
