Project Management Starts

I am looking forward to this class since I have worked with alot of project managers and would like a better understanding of what they did. They recommended it to me as a career but I was unsure if a) I could do the work and b) if it was something I would enjoy doing for the next 20 or so years. I, of course, was sent the wrong version of the text and will not receive it until Wed or Thurs but at least I will have it in time to contribute in my group this week. I am also nervous about the workload since this is the first of the 4 week courses. I hope I will be able to keep up.
