Based on many interviews with people confronted with difficult challenges (such as illness or accidents), the sociologist Antonovsky has developed a theory of what people need in order to feel good, be healthy, and cope effectively with challenges. He called this a “sense of coherence”. Having such a sense means that people feel that life is comprehensible (i.e. they understand how the world functions), manageable (i.e. they have access to the necessary skills and resources) and meaningful (i.e. they have goals worth striving for).
