I think time plays a role. Trying to learn complicated stuff fast usually leads to not learning them well enough, in my experience. If I do so, jumping to wrong conclusions or applying a method on the wrong place/in the wrong way is almost guaranteed. So just keep reading, studying, picture yourself explaining it to a classroom, talk about it to colleagues and friends, engage on discussions about it online. Eventually you'll master the craft before you know it, and the good part is that such things may be on constant evolution and there will always be something new to learn. Just avoid being that one trick pony that knows a lot about one specific topic and that's it.
