Almost 20 years ago, thanks to an international business class, I learned that India — with over 1 billion people at that time — already had a middle class the size of the entire US population (400 million). That stat has stayed me with and guided my thinking about globalization and the impact of large population nations leading our global economic growth. What does this all have to do with personal growth? A lot. How we communicate, and the impact of our communications, can change the course of our destiny and determine our success in life relationships.
