Librarian’s are masters of Self Education.
There are two types of education.
The kind you get from a school. This is a guided experience that exposes you to ideas outside your own interests, and it forces you to look at the wider world of knowledge. This is important, because we all need to be challenged if we wish to grow. This is Standardized Education. It is proved by degrees awarded by institutions. Teachers are masters of standardized education.
Then there is the kind you get from pursuing your own interests. This kind of education is harder to prove that you have. It is harder to credit to a specific institution. It is absolutely necessary for us to succeed. It is acquired by trial and error and by consuming information materials. These materials could be a Youtube video, a book or a podcast. Librarians are masters of this other education, self education.
