How to deal with and work with the people who have negative qualities like aggression, jealousy, instability and so on?

Sri Sri Ravi Shankar:

Skillfully. See that you don’t react to them but with compassion, see how you can work with them. Yeah? One thing is it can improve your skills. Second is it can improve your patience. You can gain patience. Third is it will make you realize that the person is not constantly jealous or angry. They also change! You will see and wonder on how people change!
