Quality is not an act, it is a habit.

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

Without hard work, nothing grows but weeds.

Always desire to learn something useful.

Problems are not stop signs, they are guidelines.

To know oneself, one should assert oneself.

Know or listen to those who know.

If you've got a talent, protect it.

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