Why is missing out more painful than being stuck?
From a psychological perspective, it's quite simple: because in a person's mind, being stuck at least holds some hope. Hope is particularly important; as long as you have hope, you can endure all kinds of suffering. No matter how much you've lost, you can grit your teeth and persist. However, missing out is different; missing out is completely hopeless. You have no chips in hand, what hope do you have? You can only hope for a drop, but what if it doesn't drop? Then you can only be anxious.
After all, in your mind, the extent of the rise should reflect your own profit. What you should have but didn't get—do you know how heart-wrenching that kind of pain is?
You will always think, if I had gone all in, I could have earned so much money, I could have bought this and that. Unfortunately, I didn't; I can only watch those around me rejoice.
This kind of pain, the pain of having no hope—who else can understand it if they are not the one experiencing it?
