Amazing book on the meaning of life from the founder of logotherapy (therapy based on helping clients to find meaning in their life) who is also a holocaust survivor.

The first 2/3 of the book is an autobiography about his experiences in the concentration camps and the psychological mindset of the prisoners. The last 1/3 takes his experiences and outlines the basis for which logotherapy lies. Reading it was a profound experience. It's the kind of book that you will think back to a few times a month for the rest of your life.
