Be kind whenever possible. It is always possible.

By failing to prepare, you are preparing to fail.

Never complain and never explain.

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

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

If you've got a talent, protect it.

To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

Begin to be now what you will be hereafter.
