Trust is magical, especially in trust-deficient societies.

If you are not used to being trusted, and people trust you, it does wonders.
And the opposite is also true.
If you show people that you trusted them, and they let you down, they rise to the situation a lot better.

I deploy this as a leader.

Whenever any of my team members does anything that defies our agreements, I do not reprimand them. Because there is no point in doing so.

I instead tell them, what I truly believe:
?”I trusted you. And you let me down”

Nothing works more effectively than hearing this.
Nothing makes them harder to never repeat it, than hearing this.
