With 116 brief meditations attempting to inspire the reader to flee abstractions and over-thinking and to free themselves to live in the moment and take action, naturally some of meditations were interesting and helpful and others were quite trite. Heavy with quotes about action from literary and historical figures - which are some of the best parts - this book will likely motivate you or at least fan the flame of taking some leap to pursue an action for which you have previously been unable to get off the ground.
My philosophy of life differs from Kyle Eschenroeder's, so I have some fundamental objections to much of his advice. Drawing from Marcus Aurelius, Nietzsche, eastern religions, Nassim Taleb, and a range of other sources (while somewhat contradictorily despising reading and thinking), Kyle seems to encourage a life that whirls and bounces between a life of doing - doing anything - that ultimately must never be satisfied. Ultimately even, never at rest. Without some philosophical base beyond oneself, with all the focus on oneself, I am afraid you will be disappointed still at the end of life, no matter how much action you took, no matter how many adventures, no matter how many successes, no matter how many things learned for your own self-improvement for failures.
Encouraging focusing on oneself and rejecting the power, wisdom, and aid from outside yourself that can come from reading, religion, rest, contentment, thankfulness, and fellowship is a particular weak point of this book's advice.
