This book is really one of those books where it's in your hands of how good it is. For some, it will be a great layout of reflection, introspection, and knowledge. For others, it will be a book they got started on, and it never really took off, and that's okay, but that's just the type of book this is.
It contains a daily question for each day and gives you a short paragraph each month of old wisdom from ancient times. Philosophers such as Epictetus, Marcus Aurelius, and Seneca. So, if you're looking to expand on your introspection and explore some of the ancients' wisdom, I'd recommend this book.
