How useful it would be if they also asked: "Do you suffer from unhappiness, from pessimism?" It is here that science should provide an answer to this fundamental question by Norman Cousins:
"Just as despair sets the stage for its own omens, so reasoned hope provides the essential nutrients for a flowering of the spirit that enhances life, thereby contributing regenerative energies to the shared living environment." (See his preface to my book Most of All, They Taught Me Happiness).
In other words: pessimism feeds pessimism and breeds unhappiness, failure, sickness and death; optimism feeds optimism and begets happiness, success, health and a beautiful life.
