When I say "change your world" I don't mean big, sweeping, global change -- although that's possible. I'm referring to the little changes... making a little more money, falling in love, improving your health. They make a huge difference in *your* world, but not necessarily to the world at large.
It's like trying to balance while walking on a teeter board. If you move your left foot, you must move your right foot, or you'll fall. You can't do only inner work, or only outer work. You have to do both.
