Happiness is a psychological feeling. It is attained when your expectations are met.

Internal happiness is peace, it is attained when you facilitate a fellow human being ease their pain, assist them with their work or simply by making someone else’s day. Peace is when you perform a good deed for someone else.

Selfish people rarely get to experience such feelings.

In the picture, you seem to be at peace. This is all due to the out of the way help you are doing for fellow steemians and for the steemit platform.
