Choose one advocacy cause that interests you and that is relevant to your community. What can be done?
All communities have issues and difficulties. So, all you need to do is open your eyes, talk to people, and see what the needs are. For my area, the two biggest needs are jobs and elderly care. So, if you want to act as an advocate for these causes, you will think of ways to help these groups.
Here are two suggestions on the unemployment issue.
First, you can partner with companies and schools in your area and host workshops on various issues that relate to jobs. For example, you can have people help with resumes, interviews, and the like. You might also have people in certain fields that can act as consultants. Something as simple as this can bring a lot of help.
Second, you might want to take a step further and even host a job fair. For this to happen, you will need to do a little leg work and see what companies would like to come and offer jobs.
Finally, as you do more of these types of things, you will gain more insights, experience, and networking abilities.
Hunger, homelessness, and domestic violence are three major concerns in many communities today. What are the present resources in your particular community? How might those resources be expanded? For example, are there restaurants or supermarkets that do not give to food banks? How might they be encouraged to do so? Is there a need for expansion of homeless shelters? Could a fund-raising effort be made through social media? Is there a shelter for victims of domestic abuse? if not, how could one be started? If so, what additional needs does the shelter have, for example, for clothing, for relocation services, or for legal assistance? Most communities today have thorny social problems that are in need of advocacy. This requires a combination of good public relations, networking, and just plain begging for help.
