To know oneself, one should assert oneself.

Only the educated are free.

Know or listen to those who know.

Be thine own palace, or the world's thy jail.

What you do today can improve all your tomorrows.

Go for it now. The future is promised to no one.

The wise does at once what the fool does at last.

Either you run the day or the day runs you.

Well done is better than well said.
