I second what @Gio said. And if you have particular difficulties with any lesson in any module you can write comments right under the specific video there. I witness to the fact that Josh would always respond in a couple of days.
Reading comments also helps to see if anyone else is struggling with the same issues…
Josh also has made a video particularly on muting technique
You can find a list of all the youtube material matching to B2B course map with this thread from @eric.kiser
Good luck and welcome!
Later maybe I can pick your brains on “how to make my wife play the keyboard for me” because that is what I am struggling on…
