To know oneself, one should assert oneself.

Always desire to learn something useful.

Know or listen to those who know.

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

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

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

Only the educated are free.

Things do not happen. Things are made to happen.

If you're going through hell, keep going.
