I finished it in no time because I liked the step-by-step learning method and the practical lectures that understood the learner's mind. It took a lot of time and effort to prepare for the practical lectures, not the reference document lectures. If you are a Spring practitioner, I think it will be very helpful for a deeper understanding of Spring. This lecture is so suitable for me that I plan to take all the lectures on the related roadmap. I know you are busy, but I hope you will continue to give good lectures in the future.
