An environment of pain, suffering, and violence

I motivate myself with self abuse when I work out. I scream, grunt, and curse. I like loud music when I lift weights. I am trying to create an environment of pain, suffering, and violence when I work out. It works pretty well for me. Working out is usually a social activity but for me perhaps, exercise should be a solitary activity.
I was in the weight room the other day trying to motivate myself between sets and began talking to myself: "You said you wanted to step up the ************* intensity, so step it up!"
I thought I was speaking under my breath but the opened-mouth stare of a man just a few feet from me told me otherwise. I immediately explained between laughs that I was talking to myself and meant no offense. I suppose I was lucky he wasn't bigger.
