I justify my laziness thinking that somewhere in the universe whole planetary systems are disappearing due to their mother stars exploding so it's insignificant to not study for an exam.
That's so excessive. why is your perspective like this?
It's all over the world everyday happening at the same place. It will always come to an end sooner or later, how does it matter. Could you help me to understand the solution of this equation?
You're not completely wrong but I think it's important to study universe and stuff. It makes you realize that how small and insignificant we are. It is difficult to wrap your head around the vastness of this universe.
Ok I see the point.
This turned into something quite philosophical, huh? It's awesome to think of things this way sometimes, it can really exercise the brain. But you should still take care of your duties before thinking like this so you don't get carried away.
