To know oneself, one should assert oneself.
The dog that trots about finds a bone.
Be gentle to all and stern with yourself.
If you can dream it, you can do it.
Either you run the day or the day runs you.
If you've got a talent, protect it.
The wise does at once what the fool does at last.
If you're going through hell, keep going.
Always desire to learn something useful.
By failing to prepare, you are preparing to fail.

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.
