It is not about getting smarter. It is about transferring knowledge. For that, the teaching person must a) have the knowledge, and b) the skills to actually transfer it. Both do not come easy and cheap.
You simply pay a professional person money for professional work. And sometimes it is really, really worth it. I learned one programming language in an expensive three day course - from the person who wrote the actual tools. This was intense. The amount of knowledge and insight gained was marvelous. And well worth the money.
