There's nothing more powerful than a changed mind. And I'm not talking about changing your client's mind. I'm talking about changing your own mind. Because success is in your mind. You decide when you are happy. You decide when you are unhappy. You may think it's your children, it's your client, it's someone else who gives you happiness. But imagine if someone who gives you happiness, you're giving the remote control of your happiness to them. The same people who make you happy have a power to make you unhappy. Happy, unhappy, happy, unhappy. Right? You don't ever want to give control of your happiness.
