This post might as well be describing me to the point that I feel both happy and sad. It feels so “wrong” to me to not share knowledge that I know can help someone else on my team immediately to the point that it becomes difficult to do what I am supposed to do. I don’t know what I should do. Is there a book or a video that I can learn from? Maybe a mentor? Or, am I stuck being glue?
