Now You Tell Me, Jordin Sparks

I cleaned my room today, and found this quote attached to one of essays I wrote from a professor:

I have come to the frightening conclusion that I am the decisive element. It is my personal approach that creates the climate. It is my daily mood that makes the weather. I possess tremendous power to make a life miserable or joyous. I can be a tool of torture or an instrument of inspiration. I can humiliate or humor, hurt or heal. In all situations it is my response that decides whether a crisis will be escalated or de-escalated, and a person humanized or de-humanized.
