G-Dragon confessed that he's been so pressured by his upcoming solo concert that he's been losing sleep.

He held a press conference at KBS Sports World in Hwagok-dong, Gangseo-gu, Seoul for the opening of his upcoming '2012 G-Dragon World Tour: One of a Kind' where he expressed, "It's been a dream of mine since I was young. Thankfully, since I had a world tour with Big Bang, I had a little more time to prepare for this. I'm personally looking forward to it."

G-Dragon also added, "If there's one thing I'm worried about, it's that I have to fill up 2-2.5 hour by myself. The staff are ready, but I think my preparations are lacking. I have to work harder. I felt a lot of pressure. I think so much that I get insomnia. It's not that I get scared because of the pressure. Doing that doesn't help me. I try to prepare a lot by forgetting it. I think I can keep showing a different side. I'm controlling my mind, so I don't think of anything bad."

This will be G-Dragon's first solo concert since 'Shine A Light', and he'll be kicking it off in Seoul Olympic Gymnastic Hall on March 30 and 31.
