If you genuinely care about your cause, you have the potential to be an effective advocate. Advocacy requires a great deal of patience, perseverance and persuasion. When you are passionate about your cause, this will be evident to your audience, and your message will come across more strongly and clearly. While you are an undergraduate, spend some time thinking about the causes in life that are most important to you. Perhaps you want to help end veteran homelessness, speak up on behalf of children with autism, or improve federal oversight for the food supply to reduce preventable food poisoning deaths. Whatever it is that sparks your interest and drive, there will be ways of building a career out of it.
