The Sunk Cost Fallacy

I think when the sunk cost fallacy is really happening, you don't know. You have no idea. I see stuff where people started doing something and they weren't thinking real hard about it. And now it's breaking, but they will not walk away from that thing because they just have so much time in it. They broke relationships over it with other people they cared about to acknowledge, oh, nuts. Would it be to acknowledge that they were wrong in everything they've thrown their energy at? That's tough. But also some things are true and real. Just because it's hard to go through life pursuing something doesn't mean it's sunk cost either.
