Advice
I would have to say, establish good relationships with your coworkers. Be friendly, polite, helpful, and sensitive. It's good to talk with your coworkers and get to know them but beware of gossiping and complaining. Be careful about bringing personal business to work, and be sure that what you do discuss is fit for public consumption. Furthermore, take advantage of the transition time at the beginning of any internship and ask lots of questions. You are not expected to know what is going on right away, but the faster you learn the ins and outs of daily life on the job, the better off you'll be.
