Can People Be Too Ambitious?

Although ambition often gives people motivation to strive for something, in my opinion, I do not think that being overly ambitious will give a positive result. When people tend to be too ambitious, they see nothing but only their goal. In this case, they might unintentionally ignore some critical drawbacks that could become a harm to themselves and eventually make them fail. Furthermore, when being ambitious, people often have a great chance to break relationships that they established. Macbeth, for instance, killed Banquo because he thought that Banquo might be an obstacle of this future of ascending to the throne, however, he eventually got troubled by the spirits and completely changed his destiny. In general, people are not supposed to be too ambitious in order to have a better future.
