A woman who came to a psychologist for help complained about the things she didn't have. - I don't even have good friends. The salary is not high enough. No nice car. There is no nice apartment. If there is no spouse, youth is gone, and there is no hope of getting these things in the future, the psychologist said, "Well, you have a lot of things that you don't have, shall I continue?" You don't have an incurable disease, you don't have unbearable debts, you don't have responsibilities to take on someone else's behalf, you don't have a bent back, etc. You don't have many things. "You write down these things you don't have and read them, your mood will improve and you will have hope that these things do not exist for you and will not even exist." The woman thought for a while, smiled and left.
