Sad realization

I just realized something this morning while I was working out...In the workout I do, there's a series of kicks and punches you go through. I've conditioned myself to thinking of someone I hate when I punch. Conditioned to the point where I had a couple people I'd always cycle through and not give it a second thought. But today while I was doing them, I started focusing/thinking about who I was punching at...and I realized I was imagining myself. :-(
