"We get to change our culture by how we live individually and in community every day."
Marriage equality is a great case study in this. Read the book Winning Marriage, whose author, Marc Solomon, is one of the key architects of the marriage equality movement. For a much shorter read, the environmental organization Greenpeace has a great article on how social change happens.
Remember, though, that it happens differently every time. So no one can really predict how change will occur today. There isn’t really a road map—only tools. Learn, and then trust yourself to innovate and find a way.
6. Strengthen your optimism muscle
According to Sonja Lyubomirsky, author of The How of Happiness, if you are optimistic about your goals for yourself and the world, then you are more likely to put effort into achieving them. You will also keep trying, even when you perceive the obstacles and setbacks.
This isn’t to say that you can’t be angry or have grief at the same time.
"Being optimistic is not about painting a rosy picture of the world. It’s about believing in your power to change things."
