I found Meanings of Life by Roy Baumeister very helpful to sort out what exactly to expect from meaning of life and how to get it. It is somewhat interdisciplinary but primarily a psychological study of what people who have a sense of meaning in life mean by it and how they acquire it. In style, it reminds me of a book-length Much More Than You Wanted To Know post on ACX.
