Never complain and never explain.

Problems are not stop signs, they are guidelines.

Always desire to learn something useful.

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

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

Be kind whenever possible. It is always possible.

Know or listen to those who know.

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

To know oneself, one should assert oneself.
