Positive Vibrations by Cedella Marley, A Nice Time
It is way easier to be kind than it is to be mad, angry or frustrated. While it might seem normal to react aggressively to those who are being rude and negative, try and respond with kindness.
Not only will you feel better, you will stop hurting others by refusing to participate in the same behavior. Lead by example and be the strong one in life who brings positivity and forgiveness to the world.
