" But what does it really mean to be good? Is it finding a calling that helps other people? Is it running to the bedside of someone who is dying? Is it putting someone else's needs before your own. You could argue, I suppose, that any of those actions are about not selflessness, but martyrdom. Driven not by ethics, but guilt. For that matter, what does it mean to be immoral? Is it pursuing your own dreams at all costs? Is it lying to others, or lying to yourself? [...] I know this much - morality is meant to be a clear line, but it's not really. Things change. Shit happens. Who we are is about not what we do, but why we tell ourselves we do it. "
