Be thine own palace, or the world's thy jail.
It's always too early to quit.
Be gentle to all and stern with yourself.
If you think you can do it, you can.
Either you run the day or the day runs you.
The wise does at once what the fool does at last.
Wherever you are - be all there.
Without hard work, nothing grows but weeds.
Never complain and never explain.
Be kind whenever possible. It is always possible.

I'm a bit jealous. Until two days ago someone told me I am the most famous Korean in the world.
The world's most famous and popular language is music.
