"Hurt" by Johnny Cash

This is a song by Johnny Cash, a cover of a Nine Inch Nails song. I'd heard this song a long time ago, and was re-introduced to it by Dusty. I'm going to say it, I love this song. With a passion. It's a very powerful lament of life, helped in no small part by Cash's powerful, time-worn voice.
I've made some bad choices in my life recently (not drugs or anything, bad academic choices), and this song helped me to realize what I always tell myself: you make the choices you make. Telling yourself is definitely not the same as being told by someone else, or even a song. Nothing can change what you've done. All you can do is figure out what to do next.
