Most self help books have little to do with philosophy.
They don't tell you what they believe is right based on the philosophical system they follow, they tell you what is 'good' for you. Just literally what makes you feel good, even if its a complete lie, just to make you fill fulfilled and to buy the next book.
This book is trash and so is the author. As far as I remember he once did a YouTube video where he ranked different philosophies. Seems like he took it down. And when watching it you noticed that he had absolutely no idea. Not even the basics. His idea of Stoicism was 'Suppressing all emotion until you become emotionless.' I mean bro... If you write trashy self help at least know the basic of Stoicism.
