The wise does at once what the fool does at last.
Know or listen to those who know.
Who seeks shall find.
Expect problems and eat them for breakfast.
Be thine own palace, or the world's thy jail.
Always desire to learn something useful.
The secret of getting ahead is getting started.
Be kind whenever possible. It is always possible.
To know oneself, one should assert oneself.
Only the educated are free.
