Did you trust your process the first time you did it? But I think to be clear it isn't mean to be a teaching video (and I'm pretty sure he says as much). More of a vlog and just sharing his experience. That can be very helpful too. I first got into framebuilding after watching Pithy Bikes. He was a complete amateur, made lots of mistakes, and I didn't copy his processes at all (some people just have different styles of doing things-- I'm certainly not claiming mine is better!) but it was very inspiring to watch and planted the idea.
