The State of Mind!

Control the mind. When you control it, you control everything. And it affects the things around you. For instance :-

My locker, when I'm fully tensed with exams and crap

My locker, again, when I'm at serenity NOT serenti =P

And as a bonus, senang nak study!

Conclusion: Treat your mind, don't let your surroundings get you and kill you from the inside. Thus, hypothesis is accepted.
