I remember I once lost $11K in a single session and the next morning was taking subway. Next to me sat 2 young girls and they were discussing their plans for the weekend. They were going to get away from the city to some village a couple of hundred kilometers away and they were discussing how to get there. Finally the decided to go by bus rather than train. Train although more comfortable was about $2 more expensive and they could use that money to buy a couple of beers.
They seemed so happy and fulfilled and I was just numb after losing $11K.
You’ll go crazy if you start thinking what you could have afforded with the money you lost. Don’t do that to yourself. Let it go. That money is gone. You’ll never win it back. What you will do instead, if you try, is lose more. But you already know that.
