Is going to work really a painful thing to bear?

Going to work is a painful thing that has to be endured. But how to turn this pain into happiness is to treat work as a kind of happiness.

Once upon a time, there were three people with two packages on their backs, one called happiness and the other called pain. The first person carries a happy bag behind him and a painful bag in front of him, so he walks slowly and painfully. The second man was carrying a happy bag in front and a painful bag in the back, so he walked faster and was very happy. The third man carried the happy bag in front, the painful bag in the back, poked a hole, and walked happily, singing while walking.

This story shows that people's mentality is the pillar that makes you happy or happy.
