Personally, I want to place great significance on having completed an entire book within a set timeframe. While I didn't fully understand all the content or become familiar with everything in the book, I think it was a process of learning and self-studying through Vibe Coding's approach.

It was great to be able to learn appropriate weekly content along with the habit of reading books every day! It was also good to realize that you don't necessarily have to learn something from external sources, and that this can actually increase your willingness to learn autonomously.

It was great to be able to learn about Claude in a semi-forced way through the challenge. I think it will be very helpful when using other AI tools as well.

When I signed up for the paid challenge course, it was a bit disappointing that there weren't any additional videos or materials included. However, I think the good thing about the challenge format was that it motivated me to make an effort to watch it bit by bit during my busy days. The book content seems great because it has many usage tips and useful tricks that I had been missing. Thank you for publishing such a good book!

If I had studied the book alone, it would have been difficult to complete it in a month. Thanks to the challenge, I was able to complete the study.^^ I recommend the challenge for solo studying. Although there was some lacking content in the book, I think it was an opportunity to grow from being a vibe coder to becoming a vibe engineer.
