Frankly, I'd never stumble upon this book if it wasn't recommended to me by my boss and he's learned about it as its author is his former colleague.
I really like the simplicity of this book as it aims to teach new engineers the very basics of what it takes to become successful. Though I need to argue that some of the approaches that the author talks about are controversial. Nevertheless, as the author is an accomplished individual I don't mind that he forces the reader to look at the software world from his perspective.
I wish I had this book when I was a fresh grad, it'd have made my career advance much faster and with much less bumps. Although I don't mind learning from own experience. However, I won't mind to be taught on someone else's mistakes.
This was supposed to be a soft-skills book, but surprisingly I learned a few technical tricks from it as well.
My score is 5/5 Every developer should read this book.
