It's always too early to quit.

Know or listen to those who know.

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

Either you run the day or the day runs you.

The most effective way to do it, is to do it.

Quality is not an act, it is a habit.

To know oneself, one should assert oneself.

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

Who seeks shall find.
