Business Magazines
A client of mine, along with having an import business, is also a lecturer at San Francisco State, and invited me to come in and speak to her students about my experiences when I was Asia Marketing Manager for Tyco/Raychem. I have worked as a lecturer myself (for University of Phoenix) and enjoyed standing in front of students again.
In response to a question, I advised the students to get in the habit of reading business magazines constantly. Here are the ones I recommended:


Wall Street Journal - Ok, I actually can't comment too much about this. I never had the time to read a daily newspaper in depth (I do subscribe to the local paper, but I skim most of it).
Note - the links I included should go to free trial offers for each of the magazines, so feel free to give them a try and see which you like.
