To excel in your career, don't rely on past knowledge to get you through future scenarios. You must constantly be learning and building on your knowledge base.
Know matter what your education was, situations at work will always be different and highlight specific challenges. The best thing you can do is be prepared for anything.
One of the easiest way to apply the always be learning philosophy is to be constantly asking questions whilst at work. Ask why things are this way, make suggestions and challenge management or processes, topics, etc.
