Kindness is the cause of all anxiety.

People who are prone to guilt tend to work harder and perform better than people who are not guilt-prone, and are perceived to be more capable leaders.

Forgive yourself and be ready to forgive yourself in the future. You're gonna screw up. It's okay.

The biggest mistake you can make in trying to talk convincingly is to put your highest priority on expressing your ideas and feelings. What most people really want is to be listened to, respected, and understood. The moment people see that they are being understood, they become more motivated to understand your point of view.

An attitude of self-love and relaxation facilitates this, whereas guilt often interferes.
