I wanted to post a picture of the conference that I went with my friends today but the cellphone is stuck. So his name is Dan Ariely, he is an Israeli American and he is a professor of psychology and behavioral economics in Duke University. He presented in Ted talk before. He told us about his experiences like for example, he talked about how to make something unpleasant practice more bearable. For example in his case, he had to take a lot of medicine and injections every day and it is painful.Patients with severe illness at some point, depression hunts them and they don't feel everything is pointless. So in his case while he was taking an injection he watched his most favored TV show, so he linked a horrible thing with something he loved. Even if this small detail and it is obvious to anyone but doing it, it helped him.
