(Excerpt from The Subtle Art of Not Giving a F*ck by Mark Manson)
The point is this: we all must give a fuck about something, in order to value something. And to value something, we must reject what is not that something. To value X, we must reject non-X. That rejection is an inherent and necessary part of maintaining our values, and therefore our identity. We are defined by what we choose to reject. And if we reject nothing (perhaps in fear of being rejected by something ourselves), we essentially have no identity at all.
