Credibility is important in order for a person to be trusted. Credibility is also important for people who wish to lead others.
Credibility is a must-have attribute for people in leadership positions since it helps influence people's behaviors, patterns and thoughts. If the leader is not credible, others are less likely to believe what they say or teach. Being credible also helps people truly believe that the leader or person in charge is worthy of the job at hand. Credibility is also important for people who do not lead, since it portrays that the person in question is trustworthy and believable in whatever task they do.
