Later on in the story, Tyler pushes the idea of ‘self-destruction’ as being the answer as opposed to self-improvement. This is meant not in a physical self-harming sense, he is instead referring to the destruction of the ego. To Tyler, freedom comes from destroying the ego (our view of ourselves and how we think the world sees us).
The lesson here is to quit focussing so much on the self, the ego. People aren’t paying as much attention to us as we think they are, indeed they have their own problems. Egocentricity brings its own baggage, from negative attitudes, personality clashes to neuroses. We need to get rid of all the negativity and hangups holding us back. Remember the mind-body connection, if we are thinking negatively then that influences how well our bodies operate.
Tyler’s ultimate solution here is to recognise that we’ll never be complete, to understand that we’ll never be perfect. So to stop trying, let go of all the bullshit and just live life as best as you can. Do only what is important to you rather than undertaking someone else’s objectives.
