Unless you are Jesus or Buddha, there are things that will very likely make you unhappy.
e.g: eating a lot of crappy food and spending a lot of time watching tv shows are one of them. It diminishes your health, put your dopamine system in shamble and bring no meaning in your life. It's very rare people are happy in those conditions.
Again there is nothing wrong about enjoying those activities and indulging in them. The point is it's unlikely you can fill your life with it and end up satisfied.
