"Natural medicine is only useful if you believe a condition is a transitory symptom and not a permanent fixture."
So true, the starting point of every healing transformation can only be an intention (or believe) that something will change for the better. Closely related is to believe in one´s self-efficacy (after the psychologist Albert Bandura) which is just a fancy term for almost the same thing.
Usually, before I go to bed, I think about the things I want to do the next day, that I want to be kind, happy and productive. It doesn´t work all the time, but most often it does :)
