Use ChatGPT as your 2nd brain

I liked section 3 where it talks about how you can use ChatGPT to help you develop yourself and be a better programmer, Especially the part of leet code, I enjoyed exploring the website.
But for section 1 and some of section 2 was so basic, I was looking for something like how to customize ChatGPT to help me write efficient code.
The course in general is good.
