I encourage you to read this very informative article and decide for yourself if you are a social change agent in this article by George Couros entitled 5 Characteristics of a Change Agent.  Such things as having credibility and trustworthiness are included in the description. If you don't fit the description, I think you might be inspired to aspire to move in the direction this article suggests. 

I agree with George when he says: "I believe that change agents will help to create more leaders, not more followers."
