“Know Yourself” is the ability to perceive how you feel, understand your usual emotional responses to events, and understand how your emotions affect your behavior and performance at work or in your personal life. When you know yourself, you will see yourself as other people see you, and you will have a good sense of your abilities and the current difficulties you are facing.

It means to be in control of yourself, not to judge others in any way, and to be flexible and objective, and that is through clear knowledge of your values, internal motivation and constant optimism, and living in the moment.

It means to put yourself in the shoes of others to feel what they are feeling, to understand their feelings, and to make a constructive decision accordingly. The “know yourself” stage is the mainstay of “know others”. If you are not able to perceive your own emotions, you cannot read a team member's feelings or the feelings of others.

It means mastering the skills of interpersonal communication, change management, and conflict resolution. You need to empathize with others, to be considerate in making decisions, and to make them feel that you belong to them.
