So each of us has a personal happiness thermostat. Already programmed. Already programmed into our subconscious. And everyone needs to understand this. It is this thermostat, this thermostat that will regulate how happy you will be in your life. So you can have tons of money, a gorgeous home, you know, stunning sports car. You can have the best relationship, the best family, great friends. You can achieve the highest levels of success in your business, in your career. You can be at the top of your game. Whatever you play, be great at it, or your hobby. You can have tons of fun, loads of fun. You could laugh a lot. In short, you can really have the lifestyle of your dreams. But, but, but. If your subconscious happiness thermostat is not set for high, you will never be truly happy. And if by chance you are, it will not last.
