7. The general who is skilled in defence hides in the most secret recesses of the earth; he who is skilled in attack flashes forth from the topmost heights of heaven. Thus on the one hand we have ability to protect ourselves; on the other, a victory that is complete.

善守者藏於九地之下善攻者動於九天之上故能自保而全勝也

Sun Tzu

A successful military leader should be skilled in both defense and offense. By hiding in secret and difficult-to-reach places, a military leader can protect their troops and resources. At the same time, by attacking from high ground or other advantageous positions, they can gain a decisive victory. In this way, a military leader can ensure the safety of their own forces while also achieving victory.

A strong leader is skilled in both protecting the company's assets, and in strategically positioning the company for growth and success.

A successful business leader should be skilled in both protecting the company’s resources and assets, and in strategically positioning the company for growth and success. This might involve protecting the company’s intellectual property and trade secrets, while also finding opportunities for expansion and new markets. Just as a military leader needs to be skilled in both defense and offense, a business leader needs to be able to balance the need for caution and risk-taking in order to achieve success.
