Sun Tzu is saying that it is important for a leader to be both kind and honest in order to effectively manage or lead others. Without these qualities, it may be difficult to gain the trust and respect of those being managed or led.
A team cannot be effectively managed without kindness and honesty.
When managing a team, it is important to approach them with kindness and honesty. This includes being transparent about the goals and objectives of the task. This will help to build trust and morale with your team, which can be crucial for the success of any business operation. Ultimately, managing people effectively requires a balance of strong leadership and empathy, which can only be achieved through benevolence and straightforwardness.
