Change yourself, and the world will not be the same. There is no reason to preach or moralize. No one has lucrative access to the truth or goodness. But you can inspire others through your actions. You can lead by example.The World could be a better place. There is always hope. There is optimism. It is up to you. Because you can make a difference. Each and every one of us can make a change. We can all smile and that is what it takes.
