It's official: I'm an adult. I just started my first full-time internship and the experience is extremely rewarding (so far). I love the feeling of having a job and being productive. But with that, I've come to realize that my summer is basically over (so long, weekday partying), amongst other things. Here is my list of 31 things you that happen when you start working full time:
