Studying:

I admit to barely studying 90% of the time, but my last semester of classes in graduate school gave me more than enough papers and projects to work on. Study groups are great, as long as everyone actually studied ahead of time. Though it's tempting to socialize, I have found that going out to places like those trendy coffee houses and Panera-like restaurants to study with friends is great. I started going usually by myself this semester and accomplished so much (once I had gotten bored of Facebook and web browsing). I know it's public, but it's much less distracting than being at home and less boring than going to the library. Grab some headphones and keep the coffee flowing.
