Director and actress Koo Hye-sun (42) openly shares her philosophy on failure and success as a "professional N-jobber" in 'Kim Ju-ha's Day & Night.'
On the 18th episode of MBN's 'Kim Ju-ha's Day & Night' (episode 34), Koo Hye-sun introduces the hair rollers that sparked a frenzy due to their sell-out status, sharing insights into her second life as an entrepreneur.
Koo Hye-sun's hair rollers are eco-friendly products made from recyclable materials and have secured patents and even gained entry into duty-free shops, though they also faced controversy over pricing. Regarding this, Koo Hye-sun explained, "Our products are somewhat expensive because mass production is difficult. Everything is handcrafted, requiring up to four stages of processing."
In particular, Koo Hye-sun confessed, "Since I was an artist before making products, pricing art is extremely subjective. I had to calculate how many times over I needed to sell in order to overcome that subjectivity and make a profit." She further added, "I think I've started studying money. I realized, 'I knew nothing about money,' as she revealed her sincere reflections on learning the realities of being an entrepreneur."
Koo Hye-sun also gave a clear answer to the blunt question: "People often say you have 'delusional disorder' or that you speak before thinking." After admitting, "Yes, I've heard it a lot," she continued, "I think what matters is speaking out. If you don't speak, nothing happens because you didn't say anything. This is also something I understand about myself. I can be extremely lazy." Her admission surprised everyone. Especially when Koo Hye-sun said that by trying to keep her promises, she eventually made them come true in reality, all those present on set expressed deep resonance.
Additionally, as a film director with 20 years of experience, Koo Hye-sun calmly stated about the films she has made, "They were all failures," yet followed up with the surprising twist: "But failure was successful." She explained, "Through failure, I gained inner strength and became tougher. I'm not so afraid of failure anymore." Her sincere confession about never stopping new challenges left a lasting impression on everyone.
Meanwhile, when asked by Kim Ju-ha about her future goals, Koo Hye-sun pondered for a while before answering, "Resisting my appetite," which unexpectedly showcased her unique charm and filled the set with laughter.
'Kim Ju-ha's Day & Night' is a new concept issue-maker talk show that promotes "day and night, cold reason and hot passion, information and emotion." It airs every Saturday at 9:40 p.m.
Meanwhile, Koo Hye-sun married actor Ahn Jae-hyun in 2016 but divorced in 2020.
