Because you're not. You're fucking lazy. Do anything and everything you can to improve your value, because every moment counts, and guess what, jack? Once those moments are gone, they're gone for good. The time you spend reading this could've been spent cranking out a few quick pull-ups/dips, or getting started on a philosophy/psychology reading list, or shit, lacing up your shoes for going for a walk outside. Boredom does not exist. It's your brain telling you to find something to do, that's why the feeling sucks. Get creative. Get motivated, if you're not, find something to motivate you, do anything but be "bored." There is always, always something you can do to increase your value as a man and thus to society. Nobody wants to be the ungrateful fat bitch complaining how she does nothing but eat and sit on the couch because her relationship makes her "unhaaaappy."
Boredom is for betas. Take your hands off your Xbox controller and your cock and go do twenty push-ups right now.
