The lecture content is really solid and full of practical tips that can be applied directly to work, which has been a huge help. I haven't finished listening to everything yet, but just from the first part, I could feel how high the quality is. Due to my busy schedule, I've only completed about half of the course before the enrollment period ended, which is really disappointing. Since the Q&A feature is closed, I'm cautiously making this request through a course review. If possible, could you extend the enrollment period just a little bit? I'd like to listen to the remaining parts all the way through and properly absorb the material. Thank you once again for the excellent lecture!
