28. Do not repeat the tactics which have gained you one victory, but let your methods be regulated by the infinite variety of circumstances.

故其戰勝不復而應形於無窮

Sun Tzu

The quote is suggesting that a successful tactic or strategy should not be used repeatedly, but rather that one should be flexible and adapt to changing circumstances. It is often attributed to the Chinese military strategist Sun Tzu, who wrote in his famous work The Art of War: “Therefore the skillful leader subdues the enemy’s troops without any fighting; he captures their cities without laying siege to them; he overthrows their kingdom without lengthy operations in the field.” The idea is that a good leader or strategist should be able to think on their feet and adjust their tactics to fit the specific situation at hand, rather than relying on a fixed set of methods that may not be effective in all situations.

Don't just stick to the methods that have brought you market share – be prepared to adapt and evolve in response to the diversity of business circumstances.

Businesses should not rely solely on the methods that have helped them gain market share in the past, but rather that they should be prepared to adapt and evolve in response to changing circumstances. In the fast-paced and competitive world of business, it is important for organizations to be able to adapt to new market conditions, customer preferences, and other factors that can impact their success. By being open to new methods and approaches, and by being willing to change and evolve in response to changing circumstances, businesses can stay ahead of the competition and continue to thrive.
