Clear thinking requires courage rather than intelligence.

Individual psychotherapy - that is, engaging a distressed fellow human in a disciplined conversation and human relationship - requires that the therapist have the proper temperament and philosophy of life for such work. By that I mean that the therapist must be patient, modest, and a perceptive listener, rather than a talker and advice-giver.

Clear thinking requires courage rather than intelligence.

The principal act of courage is to endure and withstand dangers doggedly rather than to attack them.

Every act of conscious learning requires the willingness to suffer an injury to one's self-esteem. That is why young children, before they are aware of their own self-importance, learn so easily.

It is easier to do one's duty to others than to one's self. If you do your duty to others, you are considered reliable. If you do your duty to yourself, you are considered selfish.
