Singer IU candidly shared her experience on starting a music career early in her teens, during the January 2nd episode of SBS's "Heroes." The episode focused on the members acting as a 'one-day professor' for a high school senior class. The members were divided into two teams and were asked to present a lecture for the pending graduates. IU used her experience as a young singer in the industry for the topic of her lecture. She started, "I debuted when I was in junior high school.� I thought I'd do well, but I failed on all levels.� I thought that if I sang, everyone would listen, but nobody cared and I received a lot of hate in return. There was even one person who told me to screw off during my debut stage." She continued, "For the first time, I was disappointed in myself.� It was a precious album to me, but it failed so horribly.� I began to wonder whether my company would stop producing albums for me.� I knew that as long as I was able to sing, I didn't care whether there was an audience or not. As soon as I threw away my greed, however, an opportunity came. 'Boo' was a better fit for my age group, so we pushed the cute concept and it became a hit.� I never even thought that I'd be able to appear on variety programs, but now I'm a fixed cast member of 'Heroes.'� It's kind of shocking, but it also feels good." IU concluded her lecture with a message to the soon-to-be graduates by stating, "When you're young, you get recognition for the littlest of things.� You can't trap yourself in that; you can't expect to be forgiven for being 'young' forever. There will be a lot of people that treat you coldly when you take off your school uniform and enter society." Source + Photos: Newsen via Nate
