Somebody told me to go watch a specific course on Frontend Masters and I ended up watching over a hundred hours of courses. In addition to all the valuable practical things I learned, I was amazed at the content and it raised the bar for the level of quality I demand from learning resources. There are a lot of trash courses and books out there that aren't worth the time. Now I vet things more before diving in. That and my Jetbrains all products license :)
