I don't think that's true. Depressed people lack desire. They often barely eat and prefer to sleep as much as possible, but that varies. In some cases they don't derive significant pleasure from anything. Happy people get excited. They have appetite. If they can afford it, they'll buy a boat so they can bring their happy friends out and have a good time. Except for monks and nuns, nobody really has everything they want. Well, you could see some depressed people as having everything they want—if they lost the ability to want.
