An important feature of efficient teams is that team members trust each other. In other words, team members trust each other's character, personality, characteristics, and ability to work. This trust can create highly trusted interactive energy within the team, which will give the team members a willingness to give, trust the team's goals and pay their own responsibility and passion. If you don't trust anyone, you can't accept anyone. According to the principle of interaction, you don't trust others, and people don't trust you. Instead, you treat people in a frank and friendly way, and the other person tends to treat you the same way. Trust is the motivation to build a team. It is also a high level of confidence in the ability of the team members.
