For those of you that do not look to the supernatural to manifest happiness, but may harbor the illusion that happiness is something to be found, you will find this
TED Conference lecture interesting. Harvard psychologist Dan Gilbert studies the nature of happiness and how our choices, and even our perception of choices, affect our happiness. It does not pertain specifically to addiction, but I was able to able to apply it to my own journey. I found the 20 minute lecture entertaining.
Best wishes.
