To draw one's attention to use Coue's method you'll need to show them
Coue's spectacular cures and the rate of success. Then you should explain him/her the science and simplicity of it.
I'd comment based on what Coue himself said and little from my experience.
Faith will come only if you see yourself the results and will go away as soon as you start applying efforts or will power.
Believing yourself that the magic power of cure lies within you and that only you can cure yourself will give faith in yourself.
Above all(in most of cases) effort is the chief cause of law of reversed affect causing exactly opposite of your desire - making you lose your faith.
For example you "want" to quit drinking and the more you "try" to stop it - it increases all the more.
In short to develop faith you should:
- You should believe in Coue's method .To believe this just go over his cures and the rate of unbelievable success. He was once curing some 10,000's in a year in 1920's.
- Realize that the immense power to cure lies in you yourself.
- Do away completely with will power and effort(This alone differentiates Coue's method with everybody else's).
- Learn Coue's "trick".
