I really enjoy your channel, and your explanations are fantastic! I do have two questions for you, though. First, have you considered upgrading your setup? I see other creators in your field using digital tools like LCD screens, touch displays, and animations to make some concepts even clearer. Do you have any plans to move from a whiteboard to similar tools? Secondly, I've noticed some other channels are able to produce content more frequently. Many creators seem to hire team members or assistants who help with course creation or video production for lower costs, around 40,000 to 50,000. This setup lets them post videos regularly because the workload is shared. Is there a specific reason you haven’t opted for a similar approach? I’d love to know your perspective!
