The quality of everything we do: our physical actions, our verbal actions, and even our mental actions, depends on our motivation. That's why it's important for us to examine our motivation in our day to day life. If we cultivate respect for others and our motivation is sincere, if we develop a genuine concern for others’ well-being, then all our actions will be positive.
