An autodidact is one who teaches themselves without another present. I’ve learned most of what I’ve learned in this way. It doesn’t mean that one doesn’t learn from others. It simply means that one doesn’t have people present to teach them. I’ve used thousands of books to learn. Even though no person was present, those books were obviously written by people.
But some believe it’s difficult to learn without a teacher. I believe it’s vital to learn how to learn on ones own without help. It does much for one’s mind. Strengthens it. I’ll talk more about this later. I haven’t explored this concept.
Mikhail Tal, one of the greatest Chess players of all time, believed that studying Chess alone was way more effective, due to the lack of interference from others. I tend to love studying alone, but also love studying with others I’m compatible with.
