What words drove Goo Hara to success?

On the latest episode of Star Golden Bell, MC Ji Suk Jin asked Kara's Goo Hara what words had motivated her during her debut. Goo Hara said "When Jiyoung and I joined Kara as new members, I heard someone say 'Those two are going to make it? There are so many others that are better, but those two are going to make it?'. I wanted to cry but managed to keep it in." She continued "I wanted to become successful and then find this person to say to them 'Look at how big I have become'." The other MCs pressed her to reveal the identity of this person. Goo Hara only responded "It was a senior singer, and that's what made it even more painful." I'm sure we are all more than happy that Hara is the one who made it!
