Psychology speaks a lot about OCD (Obsessive Compulsive Disorder).
Why not focus on HCD (Happiness Compulsive Disorder)…..the desire and urge and need to be happy no matter what.
If we all could learn one thing in life, learn to be in a good mood and happy frame of mind even if things are falling apart.
If you want to control people (which we all know everyone wants to), go be happy. Do not try to make everyone happy (you are bound to fail), be happy and your state of happiness will radiate that happiness to all around you and they cannot be anything other than happy.
Hence, your happiness infected them and controlled their hurt and pain.
