You can recommend the consultation to other people after you experience the effect of consultation, overcome life crisis, and restore happiness.

You must first experience the effect of the consultation and realize that it is different from any other conventional therapies or methods. You can recommend it to other people after you find the root cause of life crisis, solve your problem on your own, and build the ability to prevent future life crisis.   

You should never force them to take the consultation since it can be hard to understand and accept the mechanism of the novel consultation without resistance and opposition.
