One huge lesson Ryan has taught me is to not be too quick to prejudge the value of a book about life based on the author's age, an inherent bias I suppose a a lot of people my age has. I am 62 years old and believe that wisdom only comes with experience and education, and experience is a function of quality and quantity. It is rare to find someone in their early 30s with such insight into life. This book is excellent and has ignited in me the desire to learn more about Stoicism. I enthusiastically recommend this book.
