Happiness is turning your hobby into a paid job

Happiness is turning your hobby into a paid job. It is partly true, because not everyone will be able to find happiness when they try to monetise their hobby. Sometime, it even make you hate what you are doing.

Is there a paid job for eating or sleeping instead? Because everyone love sleeping and eating right? Actually sort of, I know you can get paid as a food taster for trying out new snack flavor. That's what my friend did sometime.

Lastly, why don't we just turn our paid job into hobby? Maybe we will find happiness in that way.
