One of the most important traits a person can have is that of self-confidence! This is not an easy task, and if you look around, the world is filled with people who lack self confidence. A lot of it has to do with our upbringing and the environment we were brought up in...how our parents, teachers, and influences treated and responded to us. It is up to each one of us individually to build up our own self confidence, especially if we want to advance in our chosen career.
