Nam Goong Min says acting got more comfortable yet harder over the years

Nam Goong Min talked about acting during the March 23 airing of Arirang TV's 'Showbiz Korea.'

"When I was a rookie, it was even uncomfortable just sitting in a chair," he revealed. "Because I had to run over if somebody called me.  However, now, filming is so comfortable."

However, he continued, "The filming set got more comfortable, but acting is getting harder bit by bit.  I think I'm coming to realize bit by bit that acting is difficult."  You're facing more challenges!  That's a good thing for development!

He also said in relation to his charms, "I think my best charm is that I act with diligence. Whenever I think even for a moment that acting is easy or that I'm used to it, I believe I am over as an actor.  I am trying to never cut the tie to being nervous.  That might be my charm."
