There are some memories I really want to erase from my mind and there are ones I want to keep forever, not ever wanting to forget them and if I had my way, I would renew the memories to keep them ever fresh. If I could trade my memories for money, of course I would do that but I'm only going to sell off the bad ones and keep the good ones. It will be a nice thing for the world at large because the people willing to trade their bad memories will get to let them go and never again have the need to feel depressed or frustrated at those memories.
Imagine selling off the memories of when I was heartbroken due to the death of a dear one and getting money in exchange. That would be a big flex because it would result in a better life. I wouldn't need to feel the heartbreak again because I wouldn't have to think about it anymore. Not only that, but the money gotten from that trade would be used to clear off a lot of my financial issues for me. And when I don't have any financial issues to clear, I would use the money to buy food and give myself a good meal treat.
Also, I pray I never get to the stage where I will be in such a heavy financial mess that I would feel pressured to sell my good and happy memories because if I eventually get to that stage, I might also sell some of my happy memories. This is because I can't have tradable memories and remain in deep financial lack. What benefit would it give me to stay hungry while I have something from my past that I can sell and make money from?
