The question concerning what is meaning is important. There may be a number of possible definitions of meaning. I have included one meaning definition.
Meaning Definition:
In my book, Finding Meaning (3rd edition), I state that "Finding meaning is the feeling that your life is full and significant. You feel that you are making progress towards important personal goals. You perceive many of your experiences as having value and purpose" (p. 5).
Subjective Judgment
Thus, one conceptualization of meaning is that it is a subjective judgment about your life and life events with respect to significance, purpose, and value. There may be no objective evalution of finding meaning in life. It may change with a change in one's perspective on life.
