As a young leader, I made the mistake of treating change as if it were an event instead of a process. You can't just announce a change, implement it, and move on. That only causes resistance. You have to give people time and allow them to process changes.
There is a link between our physical and verbal actions and emotions. If, instead of anger, hatred and suspicion, we are moved by loving-kindness, we will naturally have greater respect for others and our actions will be non-violent.
