It possible to have too much of a good thing. Disagree

yes it is bad

Explanation:

what if you had a bunch of your favorite food and nothing else

and you ate that one food every single day, wouldn't you get

tired of it eventually? and you wouldn't have anything else because you only have that

one food!

Yes because it eventually becomes the norm. Take money for example; rich people aren't any happier than the rest of us on average. If that rich person suddenly becomes middle class, they will be much more unhappy.
