When Ken looked back on how he got in touch with gambling in his teenage, he was only gambling on cards with a small amount of money. He perceived it as entertainment only. Later, he had more and more friends betting on horseraces, and he always heard about his friends’ winning experiences. He recalled that there were one or two celebrations with friends who won money from gambling in a week. Everyone in the gathering was excited for the one who won! At that time, an impression about gambling formed: winning is an easy job! Hence, he expected himself to win as his friends, and imagined himself to be the one treating everybody a celebration meal in the future.
