Always desire to learn something useful.
To know oneself, one should assert oneself.
If you can dream it, you can do it.
Be thine own palace, or the world's thy jail.
Only the educated are free.
Be gentle to all and stern with yourself.
Never complain and never explain.
The wise does at once what the fool does at last.
The secret of getting ahead is getting started.
Leap, and the net will appear.
The attitude of physiological psychology to sensations and feelings, considered as psychical elements, is, naturally, the attitude of psychology at large.
