The workload is a lot but I can deal with that. The pressure and intensity is a little much, but it's not even making me sweat. But what I hate is that in college I had friends that smoked, and I didn't have to be shady about smoking and not tell anyone, I could smoke, walk around in town with friends, and no one would care. But in grad school because of the nature of how it is (my class mates will be my coworkers in a few years, my professors will probably be involved in where I work as well, it's all a very small network), I cannot tell ANYONE I smoke here, and I must do it in secret.
I have 3 roommates and they have no idea that I smoke, I have to do it all shady like in my bathroom, and even more so that this is an on campus apartment so I really do not want it to get out that I am smoking. It just kills me because even my close friends that I have made so far I can't tell because I can't risk it getting out to other people because my professional reputation might be at stake. Sucks.

I wish people would judge others on their performance and intelligence, and not by what they do in their spare time which obviously has no effect on either of those two. But unfortunately this is not the world we live in, and I will probably have to keep this a secret for the rest of my life due to the area of work I am going into.
And what is rather ironic is my connection is a member of the field that I am shortly entering. Seems like you gotta keep your professional/academic life and your hobby life completely separate when you hit a certain level, which really really sucks.
