The answer to your question is simple.....dont listen to anything anyone tells you to do, and do whatever it is that will make you happy. If the corporate job is something you are interested in, go for it. If you are simply doing it to get a foot in the door, I wouldnt. I have learned that in this business it is impossible to plan your career any further than a year or two in advance....things change too quickly. Find a job you enjoy now and go for it, and good luck!
