I heavily vet sources first. Reading reviews, reddit threads, about the author, looking at the curriculum, etc. Youtube and udemy have a lot of bad stuff - but there are gems as well if you're willing to wade. I've used pluralsight in the past, it was pretty good. Again, I vetted their stuff before choosing which courses to watch. I have a list of resources for learning various things, that I've been compiling for a while now. 90% of the content is free - and that's not because I have anything against paid training.
