What are the symptoms of a person who is suffering from lack of self confidence? Symptoms may be the wrong word; we could say traits. A person who is of this category would often not have it in him to do even the simplest tasks, leave alone the challenging ones. Such people should often be indulged in Building Self Confidence that would result in getting them fit to accomplish tasks that seem relatively easy. Once they get some sort of comfort in doing this, they could move on to the tougher and challenging tasks.
