Even in Toby's Spring book, the process of building up step by step is the same, and I think you can feel how much effort he put into preparing the lecture. This is not a lecture that only teaches you how to use tools like Spring or Spring Boot well, but a lecture that teaches you the philosophy of Spring and encourages you to explore the well-designed open source structure of Spring, and fosters the ability to think about how to apply it to your own code. I think you can get more if you follow the guides that are provided in between so that you can analyze more deeply on your own, rather than just watching the lecture. I'm really looking forward to the upcoming lectures, and I'd like to thank Toby again for creating such a great lecture :)
