Don't get me wrong, I am overjoyed to be done school and have a real job but there are those few things that I miss.
1) The conference in Florida. Every year at this time I would go to this conference in Florida. Beach, sun, tasty margaritas, seafood, and Mexican food better than any you can get here! Oh and the conference wasn't too bad either. I'm especially feeling sad about this since my former supervisor and lab mates left yesterday for the conference. Although there is talk at work of going to a conference in California. I'm not sure the Mexican food will be as good though.
2) The hours. My job has flex time, which means I don't need to be in at a certain time (within reason though). With grad studies, there was no within reason. My supervisor really didn't care what hours we worked, which was the downfall of some. This was great at Christmas when I would go shopping on a weekday to avoid the crowds.
3) The people. I love the people I work with now but lets face it, grad school is more laid back. We would joke around, play practical jokes on one another, etc. I guess we all have to grow up some day :)
Hmm... that's all I can think of for now.
