"Every man judges his own happiness and satisfaction with life in terms of his possession or lack of possession of those things that he considers worthwhile and valuable"

This quote by Meir Kahane talks to the idea that each person has their own definition of joy and satisfaction with life. Everyone has various worths and beliefs, and these values and beliefs determine what they consider to be worthwhile and valuable. Therefore, each person will judge their own joy and complete satisfaction with life based upon whether they possess the things that they deem to be essential. This might be material ownerships, relationships, experiences, or anything else that they value. Eventually, it is up to each individual to decide what is important to them and to aim to acquire those things in order to achieve their own personal meaning of joy and complete satisfaction with life.
