An article in the BRW has been extolling the virtues of forgetting what you know, and being open to getting new information that shakes up your perceptions. The author says that "if we refuse to let go of what we know when the knowledge is obsolete, it can interfere with our ability to keep up with the onslaught of change." Being an expert isn't always relevant anymore - you need to know who and where the disrupters to your world are, and they aren't necessarily in your industry right now.
