Want to change the world? There’re three basic ways we can make change happen:

• Draw attention to an issue. We can draw attention to something nobody knows about or explain the importance of something that people already know but don’t much care about. The risk you take in doing this is directly related to the impact you might have: Sharing a petition on Facebook is pretty tame compared with, say, whistleblowing at work.
• Stop being part of what you dislike. If a corporation does something appalling, start a general boycott, or if you’re too busy, just stop buying its products yourself. If your political representatives do something awful, tell them why you’re going to vote against them next time. If you hate poisonous gossip at work, stop taking part. Styles of interaction are infectious, and your good example might encourage others.
• Create a better alternative to whatever’s currently available. If people like what you come up with, they’ll quickly embrace it. If they don’t, get feedback and change it.
