Until we realize what we don’t know, we can’t learn anything new. When we start a new hobby or read a book on a new topic, we have no problem admitting we don’t know about it. However, we have a lot of trouble admitting we don’t know something about an area we are an “expert” in. Take a look at your strong areas and ask someone who is new to the area and someone who is more advanced about how they do things. I promise you will gain some new insight.
