A quote from Fight Club. It relates the the fundamental struggle which the narrator is going through to find himself. By his (and Tyler Durden's ) philosophy, everything that the narrator stood for, including being a consumer, working in an office, and generally having what the normal people would consider a good life, is wrong. Therefore, by destroying your former self you can be reborn through the virtue of simplicity.

The question then presents itself as to how this philosophy relates to you after you are reborn. If you stay relative to your former self, then it still applies. However, if you apply it to your new identity, then you are reverting to everything that you sought to destroy in yourself.
