Want to make a difference? Here are some tips from Peter Singer, who is worth listening to because he practices what he preaches and because he knows what it takes to make a difference. (Excerpted from this page).
1. Try to understand the public's current thinking and where it could be encouraged to go tomorrow.
2. Select a target on the basis of vulnerabilities to public opinion and the opportunities for change.
3. Set goals which are achievable. Bring about meaningful change one step at a time.
4. Establish credible sources of information and documentation. Never assume anything. Never deceive the media or the public. Maintain credibility, and don't exaggerate or hype the issue.
5. Don't divide the world into saints and sinners.
6. Seek dialogue and attempt to work together to solve problems. Position issues as problems with solutions. This is best done by presenting realistic alternatives.
7. Avoid bureaucracy.
8. Ask yourself: "Will it work?"
