The software isn't letting me rep you right now, Arthur, but your advice is right on!
OP, most of us have been there!
You're right: you need better information and advice. In general, go to the source. If you can't, get as close to the source as possible, so find people who are doing the work you want to do and ask them questions. Get internships where you can and certainly join the professional associations (while a student, you can get student rates, and see if any of your faculty are in those groups and can introduce you around!)
Also learn what the respected trade manuals or journals are in your profession and read them for free in your
college library database (not public library!). Some will be dry as dust, but learn the names of the important (or infamous!) members. Learn the common problems and debates. Formulate your own opinions about them so that you can discuss them intelligently. You'll also find data in them about trends and financial pitfalls.
A good college reference librarian can help you with the journal databases, if necessary.
All of this is extra work and money, but it will pay off handsomely in the end because in many careers, it's about networking. We hire the people we know when we can to avoid the dreaded workplace DRAMA.
