Answer and Explanation:
I believe that the most important skill in a lawyer is argument, which must be stimulated at all times, but this argument must be based on legal concepts combined with strong cognition, perception, critical thinking, logical reasoning, capacity for expression and mental control and emotional.
To stimulate these qualities, a lot of training and study is needed, where the lawyer will study the most varied legal concepts and try to apply them to known situations. This study requires a lot of reading, which will help the lawyer to develop most of the features mentioned above. For emotional control it is necessary to learn exercises of relaxation, suppression of anxiety and others that can help to maintain calm and sensibility.
