We can't change anybody but we can detect the people that say that they are going to change and the ones that are just having a new year's day kind of changes.
It means that when someone is changing from within, then we must help to create all the conditions that facilitate that change.
I have learned that if you are treating addictions (like hard drugs), the 3% normal percentage of cures for all life, was the people that would show to detox by their own decision, and not by other people influence.
The ones that were brought by the pressure of other people and did not want to get well, would never stop the vicious circle.
And yes the real statistics of people long-time exposed to hard drugs or alcohol only 3% get out of it for life(terrifying).
Like the Buddhist says "the fish dies by the mouth" for us mean only "don't eat too much", for them there is the spiritual meaning of "We must not say, what we don't intend to do", meaning you're dying mentally when you lie to yourself.
Attitudes are intentions to act, and if we don't act, it means we are lying about our real attitudes.
