“My friends, love is better than anger. Hope is better than fear. Optimism is better than despair. So let us be loving, hopeful and optimistic. And we will change the world.” Jack Layton

I think this means, we should helpful to others and do what this qoute says because we can make a better world if we believe we can. So we have to believe and we have to take action if we are going to do it.
