Kim Sook spent some time telling viewers about all her failed business ventures on the November 19 broadcast of KBS' 'Love Naggers 2'.

Kim Sook stated that she: "used to start businesses here and there without any thought. I started a clothing store once. But waking up that early to go to the market and the act of getting clothing from far places was tough. There was no time to sleep. I kept trying, but gave up after a month and a half." 

She then gave advice to a civilian guest on the show, stating: "I saw the process to be too easy. But afterward, I never tried doing business like that."
