“We had started one of these centers near the gate of the cave, but the person in charge complained about the lack of reception from the people. I suggested that we invite two pop singers to the stadium that was near the center and distribute the brochures of the welfare center among the people during the program. and tell a little about its services from behind the speaker. Two popular artists, Agassi and Sosan, kindly came for that concert. The next day, the center manager called and said that he needed help from applicants to register, and the queue outside the center was very long. It’s long. I said to myself, again, psychology and the use of positive reinforcement [B.F.] Skinner (behavioral psychologist) helped me.”
