"Do you know that there are two kinds of monsters inside everyone's head? In your head, there is this fearsome black monster called "negativity" that drains your energy and brings a train of bitter emotions like sadness, jealousy, hatred, apathy and many more. Good thing, a strong white monster grapples against the black one day and night. The white one called "positivity" wants nothing but to fill your head with love, care, sympathy, forgiveness...."

"Do they even rest?"

"No. They are both strong and want to dominate the other. But from time to time, one is in the upperhand. The temporary winner."

"Which one wins?"

"The one you feed."
