The information you are getting from various sources is mostly because someone else paid to take classes. The same applies to something like martial arts. You can learn something from a YouTube video, but it will never replace training with a master. I know that the courses I took shaved years off the learning curve. There is surely value in paying paying to learn from someone with decades or more of experience. I find all of the classes I’ve paid for to be cheap considering the time, effort, and knowledge put into them. Just paid another almost $900 for Marissa’s new class. Even for all the classes I’ve taken, I’m getting valuable information out of it.
