"Even in the common affairs of life, in love, friendship, and marriage, how little security have we when we trust our happiness in the hands of others!"

This quote by William Hazlitt speaks to the fragility of human relationships. It recommends that even in the most typical and relatively secure relationships, such as love, relationship, and marital relationship, there is no warranty of security or happiness. We can never make sure that the other individual will remain devoted, honest, and dedicated to the relationship. We should constantly understand that our happiness remains in the hands of another individual, which individual may not constantly act in our best interests. This quote functions as a pointer to be mindful and to not take our relationships for granted. It is very important to be mindful of the risks related to trusting our happiness to another person, and to be prepared for the possibility of frustration.
