There is a book by a guy who writes about theories of changes within society and about how the major changes have occured in influxes or "waves". One book he wrote is called: The Third Wave. This man's name is ALVIN TOFFLER. I think I'm going to read this book again.
Another thing I thought about when I read your post today was how every person is like a drop of water because we can come together to be the wave and we can fall together like the rain.
