How often do you do it?
When you look at it objectively, would you say that it was time well spent?
Did those 30 hours you spent watching a TV series help you to become a better person?
Now don’t get me wrong here, I am just as guilty of it as the next person.
Its fine to use watch it during some down time, (though could reading a book be better?), though we shouldn’t allow it to become a distraction.
Remember, no matter how much or little of your time you give to TV, it is time that you won’t get back.
Time that you could have spent doing something constructive.
