Anything business related. We, as technical people, don’t speak the language(s) of other folks in an office. It’s not enough to know bits/bytes/CAT5e/switches/protocols, etc. Those terms create glassy-eyed listeners when you talk to them about how you can help them get the product or service delivered faster or better. Being able to talk return on investment, cost of capital, depreciation, etc will get you much respect and you will be able to better accomplish the tasks set before you in your role as an IT professional.
A Bachelors or Masters is a great compliment for any professional. The degree indicates that you can learn, have great study habits and are up on the theory and concepts of the technology. The certs really cement that you can actually DO the job..
