Education is important. But sometimes, some people learn what they have to learn long before they are supposed to graduate. These people drop out and continue to learn in their own way. Some of them don’t even have formal education at all. For a gifted and dedicated personality, not even lack of education is an impediment.

Srinivas Ramanujan, one of the most talented mathematicians to ever exist

Srinivas Ramanujan never had any formal education in mathematics. He was entirely self-taught in advanced mathematics because he derived most of the theorems himself. He discovered many new theorems, but most of them were dismissed because nobody believed that they could be done.

But he did become one of the greatest mathematicians to ever live, and his genius is compared to Isaac Newton.

Steve Irwin, the crocodile hunter

Steve Irwin was educated only until high school. After that, everything he knew about wildlife and wild animals came from his parents and experience.
