What Does it Mean to be Self-taught?

In the end, I think it’s less important that someone be self-taught or
formally educated. The truth is that curiosity is what matters. The
desire to be self-taught is a good one, because it means that you are
actively thinking and motivated to learn. I still hold people who are
self-taught in high regard, because we often assign genius not to people
who have an extraordinary ability to learn but to those who are
incredibly tenacious in their desire to learn.
