I want to help and prove i am the best psychologist. In the selection of workers how do you identify the good chefs and the bad chefs?. Addiction is the psychology of a liar. Non smokers are better chefs than smokers. Smoking is a liability, do smokers wash the hands after smoking when nobody is watching?. That worry is absent with workers who don’t smoke. Addiction is negative personality traits, like selfishness, arrogance, greediness and others. I am an addict in recovery and my aim is perfection. I hope this information helps. Thank you.
