Hello, I’m Gi PyeongLee

But each and every one of us has a history. It is everyday history.
What and how you act today, the present day, decorates a page in your daily history.
Can you get through the day without panicking or panicking? Will you spend it negligently or will you bravely challenge it?
Are you going to do something in a better way than yesterday? Each such attitude makes its own daily history.
