"I live for the nights I can't remember. I'll die for the friends I will never forget." isn't really that great of a quote.

The second part sure.

But the "I live for the nights I can't remember" implies that you use, and enjoy the use of, some kind of...object...that would cause you to lose memory. The first thing that comes to mind would be a narcotic or alcohol of some kind. It sounds good sure, but if you have to poison yourself to have a good time, well, that's not something I'd be bragging about.
