The New Market Wizards: Conversations with America's Top Traders
by Jack D. Schwager
Worth it's weight in gold. This book literally changed my thinking and made me money.
The Master Switch: Rise and Fall of Information Empires
by Tim Wu
Compelling and tremendously insightful. Wu's grand theory of the Cycle; an evolving pattern that goes beyond boom and bust. For understanding trends, this book excels. Economic, political and social interactions are woven together and reaffirms, in my mind, everything I have come to see in technology so far. Highly recommended.
