Great! The writer explained the "The art of war" by Sun Tzu very well through stories in history, examples in business, his understanding of military management, etc. You can learn a lot of wisdom that can be applied to many fields throughout your life. Some summaries that I like:
1. Seek battle after the victory has been won 2. Be patient. 3. Knowing yourself is more important than knowing your enemy. 4. Prepare for the worst. Consider risk and price first, and then benefit. 5. 不作死就不会死。
