DID NOT FINISH: 37%

Although the title implies so, this book is not really a "guide", providing almost no advice, tools or anything similar that might be used as help to eleviate existential angst. To a lesser extent the "existentialist's" part could be questioned as well - very Kierkegaard focused with strong Christian subtext. Other philosophers (including the famous French trio) are pretty much ignored, psychology and psychiatrics are also approached from somewhat of a distrusting stance. Basically, a casual interpretation of some of Kierkegaard's writings.
