• The ability to deal constructively with reality
• The capacity to adapt to change
• A relative freedom from symptoms that are produced by tensions and anxieties
• The capacity to find more satisfaction in giving than receiving
• The capacity to relate to other people in a consistent manner with
  mutual satisfaction and helpfulness
• The capacity to sublimate, to direct one's instinctive hostile energy into creative and constructive outlets
• The capacity to love

-- William C. Menninger, M.D.
