Here is all there is to it;

They promise that "you will live life powerfully and you will live a life you love". Something like that is their guarantee if you take their so called "curriculum for living".

Here is to achieve this without taking all the courses;

Say to yourself and others that "I live life powerfully and I live a life I love". Then when you think that this description of your life is not correct:
- give up thinking that you don't have it. Because thinking that you have a life that doesn't live up to that promise is your own fault - simply because that you think it and say it.

That's really all the promise is - that you caused it yourself. Either you cause being happy or you cause being a miserable victim.
